Question

The table below represents a linear function f(x) and the equation represents a function g(x):

x

f(x)
-1

-5
0

-1
1

3


g(x)

g(x) = 4x + 2


Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

Part B: Which function has a greater y-intercept? Justify your answer.

Answer 3

can u type x and f(x) again

Answer 4

yes

Answer 5

yes

Answer 6

In a certain town, the inches of rainfall, x, on a certain day is described by two statements:
If 3 times the rainfall is increased by 2, the rainfall is still less than 26 inches.
5 plus twice the rainfall is greater than 11 inches.


Part A: Create a compound inequality to represent the rainfall range. (3 points)
Part B: Can the rainfall in this town be 4 inches? Justify your answer by solving the inequalities in
Part C: The average rainfall in another town is 5 inches, but the actual rainfall is within 4 inches of the average. Write and solve an inequality to find the range of rainfall in the town

Answer 7

x f(x)
-1 -5
0 -1
1 3

Answer 8

can u guys please help

Answer 9

ok first we need to find f(x)

Answer 10

ok

Answer 11

let f(x)=y
y=slope*x+c this is the standard equation

Answer 12

yea

Answer 13

f(x) goes by +4 each time as in -5 +4= -1 + 4 = 3

Answer 14

:)

Answer 15

so now i need help with part a

Answer 16

ok

Answer 17

Answer 19

can u help me ?????

Answer 20

me yea

Answer 21

@gorv

Answer 22

y = 2x + 30 slope (32 -30)/(1-0) = 2 when x = 0, y = 30

Answer 23

ok... for any linear equation the slope intercept form is

y = mx + b

m is the slope of the line

b is the y-intercept, or where the line cuts the y axis

so f(x) has a slope of 2
g(x) has a slope of 8

the larger the number for the slope, the steeper the line.

-25
30
f(x)
g(x)

so the questions...

so to answer question 1.

you can say, the point slope form of a line is y = mx + b. f(x) has a slope of 2 and g(x) has a slope of 8, g(x) is the line with the steepest slope.

Answer 24

we need to find slope

Answer 25

f(x) has a y intercept of 30 and g(x) has a y intercept of -25... so f(x) has the greater intercept.
hope this helps

Answer 26

slope =(f(x1)-f(x2))/(x2-x1)

Answer 27

f(x1)=-5
f(x2)=-1

Answer 28

:)

Answer 29

x1=-1
x2=0

Answer 30

so which one has the greater intercept ????/

Answer 31

nvmmm i see now thanks :))))

Answer 32

i have another problem @awesomeness812

Answer 33

g(x) has greater intercept

Answer 34
