Question

PLEASE HELP!!

We used these functions to represent the two sides of the equation:
f(x) = 3x
g(x) = 4x + 1
Graph the functions y = f(x) and y = g(x) on the same coordinate plane.

At which points are the functions y = f(x) and y = g(x) equal? What are the x-values of the solution?

How many solutions are there to the equation f(x) = g(x)? How do you know these are solutions?

Answer 1

The two functions are equal at the two graphs' points of intersection. The points of intersection are (0,1) and (2,9). The x-values of the solutions are x = 0 and x = 2.

Step-by-step explanation:

Answer 2

1. They are met on point (-1, -3)

2. They x- values of the solution is... -1

3. There is only one solution. Proof: The slope and the y intercept is different.

4. If you plug in -1 in the x, you get the same y

Step-by-step explanation:

3x = 4x +1

0 = x +1

-1 = x

plug in... y = 3(-1) = -3
