Which input value produces the same output value for the two functions on the graph?​

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

What is the product? (x2+3y+7) [yy+1)

Which is the completely factored from of xy^3-x^3y
