Homework Equations
The Attempt at a Solution
for 24. which is a quadratic function, i understand that you have to exchange the positions of x and y and solve from there...but my question is the inverse function of that quadratic for 24 is a negative number under a square root...iv tried google etc... apparently I am dealing with imaginary or complex numbers or something... my calculator keeps giving me an error whenever i try to come up with points for the table of values using the inverse function
the inverse function btw is y=±√x-3
how do i get around this? the book clearly shows that you can graph this inverse function but i can't get the y values because the negative number in square root
for 25. the inverse function is y=3√x
using the x values in table of values of -3, -2, -1, 0 ,1 ,2 ,3
can someone please do a few sample calculations and show me how to get the answer? or how they got the solutions for a few of those points? I am completely lost for question 25.
thanks
