Bryan graphed the quadratic function f(x) = –3x² – 7x + 9. Which statement correctly explains

whether the function has a minimum or maximum?

• The graph has a minimum because the x² term is positive.

• The graph has a maximum because the x² term is positive.

• The graph has a minimum because the x term is negative.

• The graph has a maximum because the x² term is negative.
