Suppose F(x) = x3 + 4x. What is F(2)?

4

4x

7

12

F(2) = (2)^3 + 4(2) Simply substitute x=2 into the given function.

= 8 + 8

= 16

Option A is incorrect because it only substitutes x=2 into the second term, resulting in a value of 8 instead of the correct value of 16.

Option B is incorrect because it incorrectly includes the variable x, which should have been substituted with the value of 2.

Option C is incorrect because it is not the complete function, and does not take into account the first term, x^3.
