Example 1
State the maximum or minimum value of for each of the following quadratic function and state the value of x at which the function is maximum or minimum. Find the maximum or minimum point and finally state axis of symmetry for each case.
(a) f(x)=−2(x−3)2+4
(b) f(x)=3(x−4)2+10
(c) f(x)=−3(x+2)2−9
(d) f(x)=−8+2(x+5)2
