Question

If f(x) = 3x 2 + 1 find f(6).

Answer 1

f(6) = 109 is the answer

Answer 2

f(6) = 109

Explanation:

If f(x) = 3x 2 + 1 we replace x with 6 in the given function

f(6) = 3×6^2 + 1 first find the second power of 6

6^2 = 36 then multiply it by 3

36 × 3 = 108 and then add 1

108 + 1 = 109
