Answer 1

A = 11

B = 8

Explanation:

The function is 2
`2x^2 + x + 5`

To determine y=A and y=B simply substitute the value of x corresponding to that y-value

A is at x = -2

At x = -2,

`\mathsf =2\left(-2\right)^2+\left(-2\right)+5`
=
`2\cdot \:4+\left(-2\right)+5`

`= 8 - 2 + 5`

`= 11`

So
`\boxed{A = 11}`

For B, note that x = 1

So y-value for x = 1 is

`y = 2\cdot \:1^2+\:1+5`

`=2\cdot \:1+1+5`

`=2+1+5`

`=8`

So
`\boxed{B=8}`
