Step-by-step explanation:
Given the function [tex]f(x)=7x+5[/tex]
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
[tex]g(x)=-7x+5[/tex]
2. To translate the function g(x) 3 units left, add 3 units to x, thus the expression for the function will be
[tex]h(x)=-7(x+3)+5\\ \\h(x)=-7x-21+5\\ \\h(x)=-7x-16[/tex]
