Answer:

When n=3 and x=−2  the answer is 11.

Step-by-step explanation:

Given:

Let p (n,x) be the function such that

[tex]p (n,x) = n + 2x^{2}[/tex]

To Find:

p (n,x) = p ( 3, -2) = ?

Solution:

[tex]p (n,x) = n + 2x^{2}[/tex]

Substituting n = 3 and x = -2 we get

[tex]p (3, -2) = 3 + 2(-2)^{2}[/tex]

Negative square gives positive number therefore (-2)²=4

[tex]p (3, -2) = 3 + 2\times 4[/tex]

[tex]p (3, -2) = 3 + 8\\p (3, -2) = 11[/tex]

When n=3 and x=−2  the answer is 11.
