Question

Suppose that f(x)=7x-3 find f(3)

Answer 1

These are step-by-step instruction for this question:

f(x)=7x-3 First, you write down the answer

f(3)=7(3)-3 Secondly, you need to substitute the x with 3

f(3)=21-3 Next, Multiply 7 to 3 which is 21

f(3)=18 Then, Subtract 21 to 3 which is 18

Answer: So f(3) is 18

Answer 2

f(x)=7x-3 find f(3)

plug in x = 3 into the function

f(3) = 7(3) - 3 = 21 - 3 = 18

Answer

f(3) = 18
