How Do You Graph the Combination of Two Functions?

Click For Summary
To graph the combination of the functions F(x) = 2x and G(x) = x + 1, first plot each function on a coordinate plane. For F(x), start at (0,0) and plot points like (1,2) and (2,4), while for G(x), begin at (0,1) and use points like (1,2) and (2,3). Next, add the corresponding y-values of each function to find points for the combined graph, resulting in points like (1,4) and (2,7). Connect these points to create a straight line representing the combined function F + G = 3x + 1, which has a slope of 3 and a y-intercept of 1. This method effectively illustrates how to graph the combination of two functions.

How exactly do you graph these?

F(x) = 2x and G(x) = x + 1; Graph (F + G).

Please help :\

F + G = 3x + 1
 


To graph the combination of two functions, we can follow these steps:

1. Plot the points for each individual function on a coordinate plane. For F(x) = 2x, we can start with the point (0,0) and then plot additional points by using the rule "multiply x by 2 and add 1" to get (1,2), (2,4), (3,6), etc. Similarly, for G(x) = x + 1, we can start with the point (0,1) and then plot additional points by adding 1 to the x-coordinate to get (1,2), (2,3), (3,4), etc.

2. Once we have plotted the points for each function, we can connect them with a straight line to graph each individual function.

3. To graph the combination of F(x) and G(x), we need to add the corresponding y-values of each function. So for the point (1,2) on F(x), we would add 2 to the y-value of (1,2) on G(x) to get the point (1,4) on the combination graph. Similarly, for the point (2,4) on F(x), we would add 4 to the y-value of (2,3) on G(x) to get the point (2,7) on the combination graph.

4. Continue this process for each point and then connect the points with a line to graph the combination of F(x) and G(x). The resulting graph would be a straight line with a slope of 3 (since we are adding 2x and x, the slope would be 3) and a y-intercept of 1 (since we are adding 1 to the y-intercept of G(x)).

I hope this helps! Let me know if you have any further questions.
