A = 9, B = 5, C = 3

the parabola opens upwards

y-intercept = 3

Step-by-step explanation:

Since the equation is f (x) = 9x^2+5x+3, you can determine what a, b, and c are by associating it with a quadratics standard form, ax^2+bx+c. The numbers correspond with each letter in the skeletal equation.

To determine whether the parabola opens up or down, you can simply look at the a value. If x > 0, the the parabola will open upwards, whereas if x < 0, the parabola will open downwards.

To determine y-intercept, just plug in the value of 0 into x and solve for y.
