Which statements about the graph of the function f(x) = -x2 - 4x + 2 are true? Select three options
The domain is {x|x S-2).
The range is {vy s 6).
The function is increasing over the interval (-00 -2).
The function is decreasing over the interval (-4,-).
The function has a positive y-intercept

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

i think it is 70

step-by-step explanation:

the answer is ! ?

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
