Alex is right
Alex is correct
To graph the function y = 5(1/2)^x + 4, we can follow these steps:
Step 1: Choose an input-output table.
We can choose different values for x and calculate the corresponding values for y.
Let's choose x = -2, -1, 0, 1, and 2.
x | y = 5(1/2)^x + 4
-----------------------
-2 | 25
-1 | 9
0 | 5
1 | 7
2 | 9
Step 2: Plot the points on a coordinate plane.
Use the values from the input-output table to plot points on the graph. The x-values will determine the horizontal position, and the corresponding y-values will determine the vertical position.
(-2, 25), (-1, 9), (0, 5), (1, 7), (2, 9)
Step 3: Draw a smooth curve passing through the points.
Connect the points with a smooth curve, which represents the function y = 5(1/2)^x + 4.
The graph should start at (0, 9) and approach the x-axis as x approaches infinity. It will be an exponential decay function.
Note: If you have access to graphing software or a graphing calculator, you can plot the function and obtain a more accurate graph.
Sure, here is a graph of the function y = 5(1/2)^x + 4:
