What is the common ratio of quad Abcd to quad Wxyz?

B. c(x)

the output for c(x) is largest at 64 (compared to 36 and 27 for j(x) and a(x) respectively)



Work Shown:

For each function, replace every x with 3 and then use PEMDAS to evaluate

Start with c(x)
c(x) = 3x^2 + 5x + 22
c(3) = 3(3)^2 + 5(3) + 22
c(3) = 3(9) + 5(3) + 22
c(3) = 27 + 15 + 22
c(3) = 64
If the input is x = 3, then the output for c(x) is 64

Then move onto j(x)
j(x) = 12*x
j(3) = 12*3
j(3) = 36
The output here is 36

Finally move onto a(x)
a(x) = 9x
a(3) = 9*3
a(3) = 27
The output is 27



In summary:
the output for c(x) is 64
the output for j(x) is 36
the output for a(x) is 27

We see that c(x)=64 is the largest output when the input is x = 3
