To find f(10), we need to substitute x = 10 into the given equation for f(x).
f(x) = 4x^2 - 4x - 20
f(10) = 4(10)^2 - 4(10) - 20
f(10) = 4(100) - 40 - 20
f(10) = 400 - 40 - 20
f(10) = 340 - 20
f(10) = 320
f(x) = 4x^2 - 4x - 20
f(10) = 4(10)^2 - 4(10) - 20
f(10) = 4(100) - 40 - 20
f(10) = 400 - 40 - 20
f(10) = 340 - 20
f(10) = 320

To negate, multiply, and then square an expression, we first negate the expression, then multiply it by itself.
For f(10), the expression is 320.
To negate the expression, we change the sign to its opposite:
-320
Then, we multiply the negated expression by itself:
(-320)^2 = 320^2 = 102,400
So, the result of negating, multiplying, and squaring f(10) is 102,400.

Apologies for the previous incorrect response. Let's calculate the correct answer.
f(x) = 4x^2 - 4x - 20
To find f(10), we substitute x = 10 into the equation:
f(10) = 4(10)^2 - 4(10) - 20
f(10) = 4(100) - 40 - 20
f(10) = 400 - 40 - 20
f(10) = 360 - 20
f(10) = 340
Therefore, f(10) = 340.
f(x) = 4x^2 - 4x - 20
To find f(10), we substitute x = 10 into the equation:
f(10) = 4(10)^2 - 4(10) - 20
f(10) = 4(100) - 40 - 20
f(10) = 400 - 40 - 20
f(10) = 360 - 20
f(10) = 340
Therefore, f(10) = 340.

To find f(-5), we need to substitute x = -5 into the given equation for f(x).
f(x) = 2x^2 + 3x
f(-5) = 2(-5)^2 + 3(-5)
f(-5) = 2(25) - 15
f(-5) = 50 - 15
f(-5) = 35
Therefore, f(-5) = 35.
f(x) = 2x^2 + 3x
f(-5) = 2(-5)^2 + 3(-5)
f(-5) = 2(25) - 15
f(-5) = 50 - 15
f(-5) = 35
Therefore, f(-5) = 35.
