Question

A child s height h (in inches) closely resembles a linear function in terms of the child's age a (in years) if the child is between the ages of 5 and 10. The height of a certain youngster is 46 inches when the child is age 5, and 55 inches at age 7. Find a linear function relating a child's height h to his or her age a. h(a) = 4.5 a + 26.5 h(a) = 4.5 a + 28.5 h(a) = 4.5 a + 30.5 h(a) = 4.5 a + 23.5 Save Find all intercepts of the graph of y = x3 + 3x2 + 3x -1 x-int(s): 1; y-int: -1 -int(s): 3,-3 ; y-int: 1 x-int(s): 0,-1 ; y-int: - 1 x-int(s): 0, plusminus 1 ; y-int: 1
