Answer 1

Answer:

It is c. or 49 if yours are not in the same order as mine.

Answer 2

Answer:

Option C is correct.

The output is 49.

Explanation:

Given the relation: $y =3x^2+1$                   ....[1]

A function is a relation in that each input has only one output.

In the given relation,  y is a function of x

for input x=4 ,

Substitute the value of x =4 in equation [1];

$y = 3 \cdot(4)^2+1$

or

$y = 3\cdot 16+1 = 48+1 =49$

therefore, for the given input the output is 49.
