State whether the function is a polynomial function or not. If it is, give its degree. If it is not, tell why not.
f(x) = 7x^4-9x^3-6

How many zeros does the function f(x)=4x3-x2+1 have

Icould really use some with this question.

15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined
