Write a quadratic function for each graph described.
the graph has x-intercept at -1 and 5/3, and the parabola pass through the point (5,40)

Step-by-step explanation:

we know that

The roots of the quadratic function (x-intercepts) are

x=-1 and x=5/3

so

we can write the equation of the parabola as

where

a is a coefficient

Remember that

The parabola pass through the point (5,40)

substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a

x=5, y=40

substitute

apply distributive property

see the attached figure to better understand the problem

the equivalent expression are always the hardest ones but you look at the gcf also
