Question

Does anyone know how to do this ? help

Answer 1

The discriminant of ff is given by:

b^2-4ac=24^2-4 (multiply)3(multiply)48=576-576=0

2

−4ac=24

2

−4⋅3⋅48=576−576=0.

How many real number zeros does ff have?

Since the discriminant of ff is \green{0}0, ff has 11 distinct real number zero. Therefore, the graph of ff touches the xx-axis once. The graph of ff is shown below
