If f (x) = 4x+5 what is f (-3)

In this question, you're solving the given function.

In this case, you would plug in "-3" to the x variable, then solve.

Solve:

f (x) = 4 (-3) + 5

f (x) = - 12 + 5

f (x) = - 7

When you're done solving, your answer should be - 7.

Answer:

f (x) = - 7

-7

Step-by-step explanation:

f (x) = 4 x + 5

f (-3) = 4 (-3) + 5

f (-3) = - 12 + 5

f (-3) = - 7
