For fx 3x2 5x 4 the parabola opens A to the left B down C

For f(x) = 3x^2 5x 4, the parabola opens _____________.

A) to the left

B) down

C) to the right

D) up

Solution

f(x) = 3x² -5x -4 , the parabola opens

D) Up

Because it is the parabola about y axis and highest degree coefficien is positive that\'s why it is up.
