Question

How to write a function that models a rectangle's area underneath a graph...?

Answer 1

A rectangle is drawn under a parabola y=45-3x^2 such that two of its vertices are on the parabola, its base lies on the x-axis, and the rectangle is above the x-axis... Determine a function that models the rectangle's area

Answer 2

Area of rectangle = length * width

width is along x-axis
length is y-value of parabola

Area = (2x)*(45-3x^2)

Answer 3

ohhh x_x

Answer 4

so the 4 is the equation of the graph ?

Answer 5

**y

Answer 6

yes

Answer 7

but what if it looked like this
