WHat is the greatest common factor (GCF) of 9 and 27

How many terms does the polynomial x^2 y^2 have

What is the sum of these mixed numbers 4 2/3+ 3 1/9

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.
