Question

F(x) = 2x2 + 6x + 1
=
Find f ( 6)

Answer 1

so substitute x with 6

y = 4 + 36 + 1

so y or f(x) would = 41

Answer 2

f(6) = 109

Explanation:

Given polynomial:

• f(x) = 2x2 + 6x + 1

To Find:

• f(6)

Solution:

Here,in order to find f(6), substitute x = 6 onto the polynomial given:

• f(x) = 2x^2 + 6x + 1
• f(6) = 2(6)^2 + 6(6) +1

Now Simplify using PEMDAS rule.

• f(6) = 2(36)+36+1
• f(6) = 72+36+1
• f(6) = 108+1
• f(6) = 109

Hence, f(6) will be 109.
