Question

What does the graph of the polynomial function tell you about the (A) sign of the leading coefficient, (B) the degree of the function, and (C) the number of real zeros? Explain your answers! A. OThe sign of the leading coefficient is negative because the end behavior is from an equation of odd degree and negative leading coefficient OThe sign of the leading coefficient is positive because the end behavior is from an equation of odd degree and positive leading coefficient. OIt is not possible to determine the sign of the leading coefficient based on the graph. B. The degree of the leading coefficient is odd because the end behavior is going in opposite directions OThe degree of the leading coefficient is even because the end behavior is going in opposite directions It is not possible to determine anything about the degree of the function based on the graph. C. This function has 4 real zeros because it changes direction 4 times ● This function has 5 real zeros because it crosses the graph five times It is not possible to determine how many real zeros this function has based on the graph.

Answer 1

Since the graph of the polynomial function rises to the left and falls to the right. therefore The leading co-efficient is negative and the degree of polynomial is odd. - (B) e. since the graph intersects the x-axis at five points. therefore The number of real zeroes is five. f(x) = x^2 + 3x - 4 since the degree of polynomial is even and the leading co-efficient is positive. therefore the graph is left - positive, right positive.
