Answer :
Final answer:
To find the value of f(5) for the function f(x) = -2x^2 + 7x - 4, substitute x = 5 in the equation. After calculating, we get f(5) = -33.
Explanation:
The problem is asking us to find the value of the function f(x) when x = 5. The function given is f(x) = -2x^2 + 7x - 4. To find f(5), we need to substitute x = 5 into the function.
It is done as follows:
f(5) = -2*(5)^2 + 7*5 - 4
After calculating we find out that f(5) = -33. So, the correct option is a) -33.
