If f(x) = 2x - 5 , Find f(3).
Substitute 3 for x then type your final answer.

Answer 1

f(3) = 1

Explanation:

You substitute 3 for x.

f(3) = 2(3) - 5

Multiply the 2 terms.

f(3) = 6 - 5

Subtract.

f(3) = 1

Answer 2

f(3)=1

Explanation:

take f(x)=2(x)-5

put a three wherever you see an x in parentheses

f(3)=2(3) - 5

simplify

f(3)=6-5

simplify

f(3)=1

answer:f(3)=1
