Question

Find the values of b such that the function has the given maximum value. (Enter your answers as a comma-separated list.)

f(x) = −x2 + bx − 25; Maximum value: 39
 
b=
 
Expert Solution
Step 1

Given function is  fx=-x2+bx-25. -------(1)

where the maximum value ymax=39.

For a quadratic equation fx=ax2+bx+c, a<0, the maximum occurs at x=-b2a.
