I can't figure this one out.

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2

Interpret the following expression (5y^2-7)^3/(2y)^2

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?
