Which is the minimum or maximum value of the given function? a. The function has a minimum value of -2 b. The function has a minimum value of 1 c. Function has a maximum value of -2 d. The function has a maximum value of 1

The function f(x) is not given, I used a different function but the approach and steps is the same .

Step-by-step explanation:

compare with the normal quadratic equation ; ax2 + bx + c = f(x)

As such, it has a minimum

hence for minimum value; x = -b/2a

x = -(-8)/2 x 2

x = 8/4 = 2

plugging the values of x in f(x) ; f(2) = 2(2)^2 -8(2) + 5

f(2) = -3, hence it has minimum value and the minimum value is -3

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
