Answer 1

Answer:

d

Step-by-step explanation:

Answer 2

Answer:

Option (d) is correct.

The value of function $f(x)=2x^2+1$ when x = 3 is 19

Step-by-step explanation:

Given: Function $f(x)=2x^2+1$

We have to find the value of function when x = 3

Cosnier the given function $f(x)=2x^2+1$

For x = 3 , we have,

$f(3)=2(3)^2+1$

Simplify, we have,

$f(3)=18+1=19$

Thus, The value of function $f(x)=2x^2+1$ when x = 3 is 19.
