Question

how do you graph the relation -2(x-3)(x+5)

Answer 1

this is a parabola which roots of x values at x = 3 and x = - 5. The parabola is concave down ( the -2 determines this) the line of symmetry for the parabola is at x=-1... which gives a turning point at (-1, 32). The y- intercept is -15. Or you could use calculus
