Sketch a sinusoidal function that passes through (0,-4) has a period of 20, an amplitude of 3, and an equation of the axis y = -1

Describe the domain and range of y=2(3)^x-2+5

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.

For problems 29 - 31 the graph of a quadratic function y=ax^2 + bx + c is shown. tell whether the discriminant of ax^2 + bx + c = 0 is positive, negative, or zero.
