Modeling with Quadratic Functions

Question 94856 • LUSD-Int Math 2(A) LT2 Rational and Irrational Numbers (A-G)

An image of a parabolic lens is projected onto a graph. The y-intercept of the graph is (0, 90), and the zeros are 5 and 9. Which equation models the function?

Answer

y = 90(x – 5)(x – 9)

y = 2(x – 5)(x – 9)

y = 90(x + 5)(x + 9)

y = 2(x + 5)(x + 9)
