Question

Answer the questions below about the quadratic function.

f(x)=-3x² + 12x-13
Does the function have a minimum or maximum value?

Answer 1

Explanation:

f(x)= -3x² + 12x-13

a= -3 and b=12 and c= -13

at x= -b/2a you have the maximum because : a < 0

x= -12/-2 = - 6 the vertex is : (-6 ; f(6) )

Answer 2

It is a maximum because the a value (-3) is negative
