Can someone explain this problem? the complex number 5+2i is a zero of a rational function. the graph of the function also has local maxima at (-1,0)(2,0) and (8,0). what is the least possible degree of the function.

I have the same problem. I think it is 4.

Igotchu on that if you still need it

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
