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

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.

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.

Apologies for the mistake. Let's recalculate the correct answer.

f(x) = 2x^2 + 3x

To find f(-5), we substitute x = -5 into the equation:

f(-5) = 2(-5)^2 + 3(-5)

f(-5) = 2(25) - 15

f(-5) = 50 - 15

f(-5) = 35

Therefore, f(-5) = 35.

To find f(-5), we substitute x = -5 into the equation:

f(-5) = 2(-5)^2 + 3(-5)

f(-5) = 2(25) + (-15)

f(-5) = 50 - 15

f(-5) = 35

Therefore, f(-5) = 35.
