1. To reflect the graph of the function f(x) over the y-axis, you should change the slope of the line in opposite. The slope of the function f(x) is 7, so the slope of the reflected function will be -7 and the expression of the reflected function will be
2. To translate the function g(x) 3 units left, add 3 units to x, thus the expression for the function will be
You can write this in a proportion way: 6/55 = x/44. Multiply both sides by 11 to get rid of the 55 and 44: 6/5 = x/4 Now, multiply both sides by 20: 5x = 24. x = 4.8
