Answer 1

d

Explanation:

Answer 2

Option (d) is correct.

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

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.
