Answer 1

im sorry i have no idea p.s i love you profile pic btw

Answer 2

It's for my sister she can't post her question

Answer 3

thanks sam and it won't let me close it i refreshed and stuff

Answer 4

@Nnesha

Answer 5

i think a is (-3, -3) cause that is where they intersect right?

Answer 6

I believe so

Answer 7

that's easy

Answer 8

and B would be (1, 1) and (-6, -6)

Answer 9

we know right away that f(x) = x

Answer 10

and to solve for the downward slope p(x), we need to use their intercepts

Answer 11

Yeah

Answer 12

If by solutions they are asking for f(x) then it is easy A) F(x) = -3

Answer 13

no

Answer 14

solution would be the point wherethey intersect right

Answer 15

solution where both lines intersect

Answer 16

yep right

Answer 17

yeah, so part A would be (-3, -3)

Answer 18

ye

Answer 19

yes right

Answer 20

ok so what I got for part B is (1, 1) and (-6, -6) I can just choose any points that are on f(x) right

Answer 21

like I said for f(x) = x
so any value of x will yield the same value for y, since f(x) is another way to represent y

Answer 22

yeah

Answer 23

what i mostly wanted help on was part C

Answer 24

so are you ready for g(x)?

Answer 25

:)

Answer 26

yeah

Answer 27

what do you think that graph represent?
is it a parabola or what?

Answer 28

parabola? what's that

and it is a curved line and exponential function

Answer 29

well that doesn't really matter, because p(x) = g(x) is the same as solving for the intersection

Answer 30

yeah when it says p(x) = g(x) its telling you that the y values are the same cause p(x) = y and g(x) = y

Answer 31

the equality represent where two equations intersect
it could be at one particular point or at many points

Answer 32

but clearly, from the graph provided it is intersecting at one point and it is at (-6, 1)
you don't even need the actual equation for the other graph, you just need to demonstrate that you know p(x) = g(x) meant at an intersection

Answer 33

the y value where they intersect is 1, but how do I justify my answer

Answer 34

p(x) = 1
g(x) = 1

Answer 35

I have the answer and stuff for part C I just don't know how to type it out ya know

Answer 36

that's all you have to say
the equality represent same values for the two functions, that is at intersection
AT intersection, two different functions (or equations) will have the same values

Answer 37

so the solution to p(x) = g(x) is 1, correct

Answer 38

how is it 1?

Answer 39

that's the y value of the coordinate where they intersect at

Answer 40

there is ONE solution, you mean?

Answer 41

see its asking for the solutions then its asking for me to justify how I got it

Answer 42

the intersection is not clearly at 1, because 1 is not a coordinate system in a 2D space

Answer 43

(-6, 1)

Answer 44

there you go

Answer 45

so (-6, 1) is the solution

Answer 46

correct
x= -6

Answer 47

y = 1

Answer 48

so I would just say

(-6, 1) is the solution because that is where lines p(x) and g(x) intersect

Answer 49

correct

Answer 50

ok thanks

Answer 51

@sammixboo ou can close this now

Answer 52

math is fun

Answer 53

Ok tell me if you still need me to post your questions

Answer 54

:)

Answer 55

sometimes @nincompoop haha

Answer 56

i just hate functions

Answer 57

radicals are fun and other things but not functions

Answer 58

learning about intersections has a lot of applications
you can use them to determine debts, salary, or even profit
and in physical sciences, you can use it to represent where two objects might hit each other

Answer 59

yeah its pretty important
