Answer the questions about the following function. X+8 x-2 f(x)= (a) Is the point (4,3) on the graph of f? (b) If x=3, what is f(x)? What point is on the graph of f? (c) If f(x) = 2, what is x? What point(s) is (are) on the graph of f? (d) What is the domain of f? (e) List the x-intercepts, if any, of the graph of f. (1) List the y-intercept, if there is one, of the graph of f. (a) Choose the correct answer below. OA. Yes, because substituting x = 4 into the given equation results in 3. OB. No, because substituting x=4 into the given equation does not result in 3. OC. Yes, because substituting x=3 into the given equation results in 4. D. No, because substituting x=3 into the given equation does not result in 4.
