The revenue for a restaurant chain (in billions of dollars) for the years 2010 to 2015 can be approximated by the following quadratic function, where x = 10 corresponds to the year 2010. ²+ R(x) = - (a) Find the vertex. (b) In what year during this period was revenue at a maximum? (c) What was the maximum revenue, to the nearest billion dollars? (a) What equation can be used to calculate the x-coordinate of the vertex? FOA X= OB. +15x-60 O.C. x= 15 X=- 1 15 (-) 15 15

Create a quadratic function in factored form and show how to convert it to standard form.

How do I rewrite this quadratic function in the vertex form and what would be the vertex? f(x)=5x^2-25x

if you vertically stretch the quadratic parent function, F(x)=x2, by multiplying by 7, what is the equation of the new function?
