According to descartes' rule of signs, how many possible real roots could the following polynomial function have? f(x)=3x^4-5x^3+5x^2+5x-2

What does the relationship between the mean and median reveal about the shape of the data

What are the domain and range of the function f(x)=2^x+1

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.
