Question

oops try this determine whether the given quadratic has a min or max value then find the min or max value and determine where it occurs f(x)=4x^2+2x+2

Answer 1

Compare it with:

ax^2 + bx + c = 0

the values of a is +4.
this means that we will have a min point.

Answer 2

min value is 7/4

Answer 3

To determine where it occurs,
use -b/2a to find it's "x" cordinate.

the value of b is 2 and a is 4.
\[-\frac{b}{2a} \to -\frac{2}{2(4)} \to -\frac{2}{8} \to -\frac14\]

Answer 4

Now insert this value in the equation to get the "y" cordinate.
