If f(x) = - 2x2 + 2x - 3, what is f(5)?

x^2 = x squared

-2x^2 + 2x - 3 = -50 + 10 - 3 = -43

To find f(5), we need to substitute 5 into the function f(x) and evaluate it.

Given that f(x) = -2x^2 + 2x - 3, we can substitute x with 5:
f(5) = -2(5)^2 + 2(5) - 3

To simplify this expression, we need to follow the order of operations, which is called BIDMAS (Brackets, Indices, Division and Multiplication, Addition and Subtraction). In this case, we will start with the exponentiation, then perform the multiplication, and finally the addition/subtraction.

First, we calculate 5 raised to the power of 2:
5^2 = 5 * 5 = 25

Next, we substitute this value into the equation:
f(5) = -2(25) + 2(5) - 3

Now, we perform the multiplications:
-2(25) = -50
2(5) = 10

Substituting these values back into the equation, we have:
f(5) = -50 + 10 - 3

Finally, we evaluate the addition/subtraction:
-50 + 10 - 3 = -43

Therefore, f(5) = -43.
