Answer:
A function is shown where b is a real number. f(x)=x^2+bx+144 The minimum value of the function is 80. Create an equation for an equivalent function in the form f(x)=(x-h)^2+k.
You can make it with 10 because 10%times 5% is 50%
Given a point in coordinates form

, one can compute the cartesian form like this:

We have:

We get the cartesian form then:
