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.
(1) List the y-intercept, if there is one, of the graph of (a) Choose the correct answer below.
A. Yes, because substituting x = 2 into the given equation results in -1.
B. No, because substituting x=2 into the given equation does not result in -1
C. No, because substituting x = -1 into the given equation does not result in 2.
D. Yes, because substituting x = -1 into the given equation results in 2.
(b) If x=2, f(x) =
