2) AD || BC
3) none

What statement is true? 2x^2-9x+2=-1

Proportions in triangles solve for x

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
