Question

HELP ASAP!! (picture above)

Answer 1

To calculate minimum value, do -b/2a to get the x-value, and plug it in to get the y-value:

-6/8 = -3/4


`4 * (-(3)/(4) )^(2) + 6 (-(3)/(4) ) - 18 = (9)/(4) - (9)/(2) - 18 = - (81)/(4)`

So the minimum value of g(x) is -81/4

This shows that g(x) has a lesser minimum value than f(x)
