Answer:
Option C is correct.
The output is 49.
Explanation:
Given the relation: [tex]y =3x^2+1[/tex] ....[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];
[tex]y = 3 \cdot(4)^2+1[/tex]
or
[tex]y = 3\cdot 16+1 = 48+1 =49[/tex]
therefore, for the given input the output is 49.
