What is the graph of the function?
y = 2 · 2x
How would I graph this. I don't understand it.
Thank You.
take a visit to

and type in your function: 2*2^x
it will show the graph. You can ;play around with various variations on things, and get a feel for how they work. Handy place to visit when trying to visualize functions.
Thank You.
To graph the function y = 2 · 2x, you can follow these steps:
1. Choose some x-values to substitute into the equation. For example, you can select x = -2, -1, 0, 1, and 2. These values will help determine different points on the graph.
2. Calculate the corresponding y-values. Substitute each selected x-value into the equation and calculate the resulting y-value. For instance, when x = -2: y = 2 · 2^(-2) = 2 · 1/4 = 1/2.
3. Plot the points. Using the x and y values calculated, plot the points on a Cartesian coordinate system. For example, if we calculate the point (-2, 1/2), plot this point on the graph.
4. Repeat steps 2 and 3 for each of the selected x-values. By computing more points, you can better understand the shape of the graph.
5. Connect the plotted points. Once you have several points plotted, draw a smooth curve or line that passes through them. This line represents the graph of the function.
Regarding this specific function, y = 2 · 2x, you will notice that for each increasing value of x, the corresponding y-value doubles. So, as x increases, the graph will grow exponentially.
By following these steps, you should be able to graph the function y = 2 · 2x effectively.
