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, <u>ax^2+bx+c</u>. 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 <u>x > 0</u>, the the parabola will <u>open upwards</u>, whereas if <u>x < 0</u>, the parabola will <u>open downwards</u>.
To determine <u>y-intercept</u>, just plug in the value of 0 into x and solve for y.
