Question

Timmy writes the equation f(x) - *x-1. He then doubles both of the terms on the right side to create the equation g(x) =

2x - 2. How does the graph of g(x) compare to the graph of f(x)?
The line of g(x) is steeper and has a higher y-intercept.
The line of g(x) is less steep and has a lower y-intercept.
The line of g(x) is steeper and has a lower y-intercept.
The line of g(x) is less steep and has a higher y-intercept.

Answer 1

The line of g(x) is steeper and has a lower y-intercept.

Explanation:

Doubling the function expands it vertically by a factor of 2. Everything is twice as far from the x-axis as it was. The line becomes steeper, and the y-intercept moves twice as far away. It was at -1, now is lower, at -2.

The line of g(x) is steeper and has a lower y-intercept.
