Question

What is f(5) if f (x) = -2x+1​

Answer 1

Answer: -9

====================================================

Step-by-step explanation:

We replace every copy of x with 5. Then we apply the order of operations PEMDAS to simplify.

f(x) = -2x+1

f(5) = -2(5)+1 ..... x replaced with 5

f(5) = -10+1

f(5) = -9
