1. Is the function /(*) => invertible? If so, find the inverse f(x) Of ( x ) = 3x Of ( x ) = 3x Of ( x ) = 3x O A(x) is not invertible. Q 2. A commercial airplane travels according to the formula () = 160, where d is the distance traveled in miles and t is the time in hours. What is the meaning of "(320)? O A commercial airplane travels at an average speed of 160 miles per hour. It takes the airplane two hours to travel 320 miles. O It takes the airplane 320 hours to travel two miles. O A commercial airplane travels at an average speed of 320 miles per hour.Q 3. Consider the graph below of the function A( x): -5 0 5 10 Using the graph, what is the value of f(1 )? Of ( 1 ) =0 Of(1 ) = 10 O Cannot be determined. Of(1) =14. Determine whether the given functions f(x) and g(x) are inverses of one another. Justify your response. AX) = x+2 and 8(x) = /3x + 2 35. Select the graph of the inverse function to the function displayed here: 20 -20 20 -20
