yeah i donty know x2

do i have enough info to complete the first, i don't really know how to go about doing it...

okay so plan old slope i would find it by doing: m = x2 -x1 / f(x2) - f(x1) or slope of secant = f(0+h) - f(0) / h m = [(o+h)-5][2(0+h)+3] - (-5)(3) / h m = (h-5)(2h+3) + 15 / h m = 2h^2 + 3h + 10h -15 +15 / h m= 2h-7 ?

here is my question, *thanks for helping* i need it badly Consider the curve y = f(x) where f(x) = (x-5)(2X+3) A) Show that P1 = (x1,y1) = (0,-15) is on the curve and find and expression for the slope of the secant joining P1 with any other point P2 = (x2,f(x2)) , x2 cannot be 0 on the...
