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
Answer
negate mulitply and square
Answered by GPT 3.5
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.
Answer
the answer is 340

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.
Answer
its wrong try again or else
Answered by GPT 3.5
Apologies for the mistake. Let's recalculate the correct answer again.

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.
