it's not a worded question, just says find the equation of the parabola, and gives the sketch...
Hi! ^_^ I'd realy appreciate some help on this question :D
Its an upside down parabola, and intersects the x axis at 5, and the y axis at 10. It also gives me the angle of inside the curve measured from the y axis up, as 70 degress, but i don't get how thats relevant :( How would I find the...
