Question

dont know what language this is. LOL

Answer 1

Let's say that f(x) = y
This then comes in the form y = mx + b
Set x = 0 to find y-intercept.

Answer 2

O.o stll confused </3

Answer 3

Zero is when we get a 0 in f(x)

Answer 4

ok

Answer 5

@UnkleRhaukus only hints please!

Answer 6

@ParthKohli ah u suck lol :)

Answer 7

This is very easy. Don't be an answer fiend.

Answer 8

We're helping you as far as we can.

Answer 9

no but really ii dont understand these sorts of questions im really really bad at functions and graphs truely, theres got to be something your bad at! SO U GOTTA UNDERSTAND! now algebra im good at that :) but this O.o

Answer 10

Okay, tell me what you get when you set x = 0

Answer 11

0

Answer 12

Let a function with input x: \(y=f(x)\)

Be defined as : \(f(x)=-\sqrt {x}+5\)

The y intercept is when the input is zero, ie x=0,

\(f(0)=-\sqrt {0}+5=\cdots\)

The zero is when \(f(x)=0\)

ie \(0=-\sqrt{x}+5\)
\[\cdots=x\]

Answer 13

ok so i feel that its D?

Answer 14

nope

Answer 15

ugh :(

Answer 16

lets find the y-intercept first: \((0,y)\)
\[y=f(x)=-\sqrt x+5\]\[f(0)=-\sqrt 0+5\]\[y=\cdots\]

Answer 17

5

Answer 18

Yes.

Answer 19

can you wright it as a orded pair? \((x,y)\)

Answer 20

0,5

Answer 21

orded pair= coordinate

Answer 22

right,

Answer 23

so its a

Answer 24

Now the zero of the function is when \(y=f(x)=0\)

so solve \( 0=−\sqrt{x}+5\)

Answer 25

idk how to solve that im sorry you probably think im mentally ill.. :( this stuff just does not come easy to me ..

Answer 26

no worries i am mental ill aslo
\[0=-\sqrt x+5\]
add \(\sqrt x\) to both sides

Answer 27

\[\sqrt x=-\sqrt x +5+ \sqrt x\]
now simplify the right hand side

Answer 28

omg idk : ( i feel like crying. really thats how fustrated i am,

Answer 29

the right hand side can be simplified to be 5
(perhaps your blood sugar is low, eat a biscuit)

Answer 30

ok i picked E i just have to move on i have a lot to do so i can graduate in 3 days :( thats why im so fustrated. I SPEND LIKE 30 minutes on like 1 question. THANKS ANYWAY I KNOW UR WERE TRYING TO HELP

Answer 31

so we have
\[\sqrt x=5\]
the next step is to get rid of the square root
to do this square both sides of the equation,
if you have done this correctly
you have found the x that zeroes the function
\[x=\cdots\]

when this is the input of the function \(f(x)\rightarrow f(\dots)=0
\)
because \( f(\dots )=-\sqrt{\cdots}+5=0\)
which you can check to be sure

Answer 32

\[({\sqrt x})^2=(5)^2\]
\[x=5^2=\cdots\]

Answer 33

NOT E

Answer 34

its ok :) thanks anyway..

Answer 35

You had already found the coordinate of the y intercept = (0,5)
which was enough to eliminate all the wrong options

Answer 36

I know i said it was A but you didnt tell me if i was correct so i thought a was wrong so then i just put E :/

Answer 37

well im not really here for multiple choice , im here for mathematics

Answer 38

I understand, thanks anyway! :) <3

Answer 39

yer
