If p(x) = 3(x²+8) + 10, what is the value of p(11)?

Hey there!

If p as a function of x is equal to:

3(x^2 + 8) + 10

If we're looking for p(11), we can plug in 11 for x to get:

3(11^2  + 8) + 10 =

3(121+8) + 10 =

3(129) + 10 =

387 + 10 =

397

Hope this helps!

Substitute 11 into x
p(11) = 3(11²+8) + 10
3(121+8)+10
3(130) + 10
390 + 10

the answer is 400.
