In the above graph you see the functions f(x) = (x+3)(x-3) , g(x) = 0,5x^2 + x + 3 and h(x) = x-3

In the above graph you see the functions f(x) = (x+3)(x-3) , g(x) = 0,5x^2 + x + 3  and h(x) = x-3

d. Calculate the x coordinates of the points of intersection of the graphs of f and g .

e. Theres the function notation j(x) = (x+ 2 1/2)^2 - 5 . Give by logically reasoning the coordinates of the top of the graph of function j

I posted this question while one of the functions wasn't written correctly whoops! So here it is again, sorry for nuisance.
