You buy five books that are equal in price and a DVD for $8. Your total
comes to $26.50. Write an equation
that would help you determine the cost
of one book.
( Hint it’s not 3.70!)
Please help!

Which equation is y = -6x2 + 3x + 2 rewritten in vertex form?

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.
