For which intervals is the function positive? Select each correct answer. MULTIPLE ANSWERS

(0,4)

(−2, 0)

(−1.5,−1)

(−∞,−2)

(2,2.5)

(4,∞)

(-infinity, -2) and (0, 4)

Step-by-step explanation:

If the graph is above the x-axis, the function is positive; if below, negative.

The function shown in the graph is positive on the intervals (-infinity, -2) and (0, 4).

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
