For each of the following functions use the quadratic formula to
find the zeros of f. Then, find the maximum or minimum
value of f(x).
(a) f(x) = x2 -
10x
Zeros of f (If there are no real zeros, enter NONE.)
... (smaller value)
.... (larger value)
Maximum or Minimum Value of f(x)
The minimum value of f(x) is
.... when x = .
(b) f(x) = -2x2
- 3x + 2
Zeros of f (If there are no real zeros, enter NONE.)
....(smaller value)...
