A quadratic function ‒x2 + bx + c attains its maximum value at x = 4. If f(‒8) = 0, then find f(10).

A quadratic function ‒x2 + bx + c attains its maximum value at x = 4. If f(‒8) = 0, then find f(10).

Determine, without graphing, whether the given quadratic function has a maximum value or a minimum value and then find that value.f(x) = -x2 + 2x - 7

Determine, without graphing, whether the given quadratic function has a maximum value or a minimum value and then find that value.f(x) = x2 + 2x - 7

Let f(x) be a real value function such that f(x)=2x−1x−2∀ x ∈ (2,∞) and g(x)=x2+1x+(f(x))2+1f(x)∀ x>2, then minimum value of g(x) is

What is the value of x, at which the quadratic function f(x)=-2x^2+8.9x-1.8 achieves its maximum? Round your answer to 2 decimal places.
