Answer the questions about the following function. (a) Choose the correct answer below. f(x) = 2x2 - x-1 O A. No, because substituting x = 9 into the given equation does not result in - 2. (a) Is the point ( - 2,9) on the graph of f? O B. Yes, because substituting x = - 2 into the given equation results in 9. (b) If x = 2, what is f(x)? What point is on the graph of f? (c) If f(x) = - 1, what is x? What point(s) are on the graph of f? O C. Yes, because substituting x = 9 into the given equation results in - 2. (d) What is the domain of f? (e) List the x-intercept(s), if any, of the graph of f. O D. No, because substituting x = - 2 into the given equation does not result in 9. (f) List the y-intercept, if there is one, of the graph of f.Answer the questions about the followmg function f _x+8 (>07)?g 13 (a) is the point 2: 7 T on the graph of f?
