Given the relation y = 7x² + 3, if the input is 4, what is the output?

Solution:

Given equation is a 2 degree equation, here we can substitute the input value as x and get the output as y.

It is given that

y = 7x² + 3

Input is 4 means that x = 4

Now substitute the x value as 4 to get the output

y = 7(4)² + 3

By further calculation

y = 7(16) + 3

So we get

y = 112 + 3

y = 115

Therefore, the output is 115.

Given the relation y = 7x² + 3, if the input is 4, what is the output?

Summary:

Given the relation y = 7x² + 3, if the input is 4, the output is 115.
