What is the equation, in point-slope form, for the line with a SLOPE of -2 that passes through the point of (1,-4)?

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Find the actual dimensions of the box. the side length are in meters and integers. the surface area of the box is 104 m2 and volume of the box is 60 m3.

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.
