Answer the questions about the following function. f(x)=3x²-x-2 (a) Is the point (-1,2) on the graph of f? (b) If x=2, what is f(x)? What point is on the graph of f? (c) If f(x) = -2, what is x? What point(s) are on the graph of f? (d) What is the domain of f? (e) List the x-intercept(s), if any, of the graph of f. (f) List the y-intercept, if there is one, of the graph of f. (a) Choose the correct answer below. A. Yes, because substituting x= -1 into the given equation results in 2. O B. No, because substituting x= -1 into the given equation does not result in 2. O C. Yes, because substituting x=2 into the given equation results in - 1. O D. No, because substituting x=2 into the given equation does not result in - 1. (b) If x=2, f(x) = (Simplify your answer.)
