Question 164176
The function y= .03X^2 + 254.50 0 
-----------------------

a) Determine the inverse of the function. What does each variable in the inverse function represent?
x = 0.03y^2 + 254.5
y = sqrt[(x-254.5)/0.03]
----------------------------
b) Use a graphing utility to graph the inverse function.
{{{graph(400,300,-10,300,-10,50,[(x-254.5)/0.03]^(0.5))}}}
----------------------------

c) Determine the percent load interval if the exhaust temperature of the engine must not exceed 500F. 
What does that have to do with the function or its inverse?
