Question

Evaluate the function when x = 3.

f(x) = 5x + 2
A. -1/5
B. 1
C. 3
D. 7

Answer 1

The Answers given are incorrect this is because the correct answer is 5.7

f(x) = 5x + 2

f(3)=5(3)+2

3f=15+2

3f=17

3f÷3=17÷3

f=5.66666666667

=5.7

Answer 2

To evaluate the function when x = 3, we substitute 3 for x in the given function f(x) = 5x + 2:

f(3) = 5(3) + 2

f(3) = 15 + 2

f(3) = 17

Therefore, when x = 3, the value of the function f(x) = 5x + 2 is 17.

So, the correct answer is option D, 7 is incorrect because 5*3+2 = 17.
