Question

What is the range of the function h(x) = -8x?

A.y < 0
B. y ≤ 0
C. y ≤ -1
D.y < -8

Answer 1

i think its A

tell me if it helps :)

Answer 2

y<0

Explanation:

`h(x)= -8^x`

Range is the set of y values for which the function is defined

We have exponent x, lets plug in some positive and negative numbers for x and check

Suppose x=-1 then
`h(-1)= -8^(-1)= -(1)/(8)`

x=1 then
`h(1)= -8^(1)=-8`

So for x values the value of h(x) is negative

For all x values , the y value is negative .

Hence range is y<0
