Question

F(x)=-2x+13 for f(-4) Evaluate

Answer 1

Answer:

f( - 4) = 21

Step-by-step explanation:

$f(x)=-2x+13$

To find f(-4), substitute the value of x that's - 4 into f(x). That is for every x in f(x) replace it with - 4

We have

$f( - 4) = - 2( - 4) + 13 \\ = 8 + 13 \\ = 21 \: \: \: \: \: \: \: \:$

We have the final answer as

f(-4) = 21
