4c2 + 7c – 5 = 0 a=4 b=7 c=-5
x = [-b +-sq root (b^2 -4ac)] / 2a
x = [-7 +-sq root(7^2 -4*4*-5)] / 2*4
x = [-7 +-sq root(49 + 80)] / 8
x = [-7 +-5.5677643628] /8
x1 = 0.544727125
x2 = -2.294727125
The standard position of a function is y = ax^n + bx^n-1 + ... k where a, b and k are all constants. In this case, the problem gives
<span>y = − one over two (x − 2)2 − 2
Translating numerically,
y = [-1/2(x-2)^2 ] -2
2(x-2)^2 y = -1 -2(2*(x-2)^2)
</span>2(x-2)^2 y= -1 -4(x^2-4x+4)
y = (-4x^2 + 16x -17) /(2(x-2)^2)
An angle is the intersection of two noncollinear rays at a common endpoint. The rays are called sides and the common endpoint is called the vertex.
