How do you find the area of a rhombus with only one side and a diagonal given

Solve the equation x/4 - 5= -8 -27 -12 -7 12

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.

What is the domain of the of the exponential function shown below?
