Question

The function h is defined by h(x)=2(x-7) what is the value of h(8)

Answer 1

h(x)=2x-14

h(8)=2(8)-14

16-14=2

the value of h(8) is 2

Answer 2

Answer:

$h(8) = 2$

Step-by-step explanation:

We have h, that is a function of x. This means that the value of h is dependent of the value of x. h(8), for example, is the value of h when x = 8. So:

$h(x) = 2(x - 7)$

$h(8) = 2(8 - 7)$

What is inside of the parenthesis takes precedence, so we have $h(8) = 2(1) = 2$
