Which of the following functions has the largest value when x = 5?

p(x) = 2x2 + 4x + 11
h(x) = 4x
s(x) = 10x

a. p(x)
b. h(x)
c. s(x)
d. all the functions are equal at x = 5.

Largest value is at p(5) is 81

Step-by-step explanation:

We have given three function

we need to check the largest value at  

substitute in p(x) we will get    we will get

Now, substitute in h(x) we wil get we will get

Similarly, substitute in s(x) we will get we will get

Now, comparing all the three values of , ,

Largest value is at p(5) is 81
