If f(x) = 2x2 + 2, find f(5).
a.) 102
b.) 52
c.) 22
d.) −1.5

option (b) is correct.

value of function at x = 5 is 52.

Step-by-step explanation:

Given function

We have to evaluate f(5) that is the value of function at x= 5.

Consider the given function  ,

To find the value of function , simply substitute the value of x as 5 ,

we get,  

On solving we get,

Thus, value of function at x = 5 is 52.

Thus, option (b) is correct.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
