Question

What is the value of f(-6) for the function f(x) = (1/2)x - 7

Answer 1

-10

Explanation:

for f(-6)

we know ,

x is -6 as we are replacing value

now

f(x)=(1/2)x-7

or f(-6)=1/2*-6-7

or,f(-6)=-3-7

to therefore f(-6)= -10

Answer 2

The answer is

`f( - 6) = - 10`

Explanation:

`f(x) = (1)/(2) x - 7`

To find f(-6) , substitute the value of x that's - 6 into f(x). That is for every x in f(x) replace it with - 6

We have

`f( - 6) = (1)/(2) ( - 6) - 7 \\ = - 3 - 7`

We have the final answer as

`f( - 6) = - 10`

Hope this helps you
