Question

If f(x) = -3 - 6x, find f(-2)

Answer 1

`\large{ \bold{f(-2)=9}}`

Explanation:

In order to find f(-2) we substitute the value of x that's -2 into f(x). That is wherever there is x in f (x) you replace it by -2 and solve.

We have

`\large{f(-2) = -3 - 6(-2)\\= -3--12 = -3+12 = 9}`

We have the final answer as

`\large{f(-2)=9}`

Hope this helps you
