Question 402714
5. Is f(x) = x^2+2x-3 a one-to-one function? Explain your answer
Ans: No. For each x there is only one y-value.
But Some y-values are the result of 2 different x-values.

6. For the polynomial f(x)= -11x^3+3x^2-x+1, what is the degree of F and what is its leading coefficent?
Ans: degree = 3 because the highest power term is x^3
leading coefficient is -11
