Question

Given the relation y = 3x^2 + 1, if the input is 4, what is the output?

Answer 1

The output is 49

Step-by-step explanation:

If the input is 4, then x = 4.

Replace x with 4 and you have the equation:

3(4)^2 + 1 = 49

Because Y is the output, and Y = 49, the output is 49

Answer 2

Explanation:

y=3(4)²+1

=48+1

=49
