Question

Solve for f(-7)
f(x)=5-x
f(7)=

Answer 1

Answer/conclusion -

`f(-7)=12`

Explanation -

When solving for a value of a function
`f(x)`, substitute the number instead of x (this number should be given to you) aand solve

The function here is
`f(x)=5-x`. Now let's get down to answering the given activity.

`f(-7)=5-(-7)`

`f(-7)=5+7` (over here the minuses cancel into +)

`=12`

Answer 2

f(7) = 12

Explanation:

When we have a number in the parentheses here, that is the x value. So, we plug in -7 for x!

f(7) = 5 - (-7)

f(7) = 5 + 7

f(7) = `12

So, our answer is:

f(7) = 12
