To find out how high I need to jump, I will use the expression y=-4x+8x+14. By using this expression, I first need to find the x-intercepts to create a parabola. To find the x-intercepts I will us the quadractic formula.
Plug in the a,b,c values in the quadratic formula and solve for x. After, find the average of the x-intercepts. to find the axis of symmetry. The axis of symmetry is 1. Sub 1 back into y=-4x + 8x +14 to find the vertex. The vertex is (1,18). By subtracting the vertex with the height of the cliff, I found out I need to jump 4 meters high to get to the other side of the canyon.
I made it ! Now I have to go to the beach to my boat.
