c) 17
d) 21

Answer 1

The output of the given relation y=x^2+1 when the input is 4 is 17.

Step-by-step explanation:

To find the output of the given relation y = x^2+1 when the input is 4, we substitute the value of x into the equation:

y = (4)^2 + 1 = 16 + 1 = 17

Therefore, the output is 17, so the correct answer is option c) 17.
