a question on a test asks students to find the speed at which a car travels. The graph shows a proportional relationship between the distance tracker in miles and time in hours. a student incorrectly says the speed of the car is 1/63 of a mile per hour. What is the speed of the car? what error did the student likely make?

1.what effect does replacing x with x−4 have on the graph for the function f(x) ? f(x)=|x−6|+2 the graph is shifted 4 units up. the graph is shifted 4 units down. the graph is shifted 4 units left. the graph is shifted 4 units right. 2.what are the coordinates of the hole in the graph of the function f(x) ? f(x)=x^2+3x−28/x+7 3.which graph represents the function?
