Alina and Skyla are both solving the equation 2x = 128. Alina knows the solution to the equation because she knows a power of 2 that equals 128.

Skyla does not know a power of 2 that equals 128, so she graphs two equations, y = 2x and y = 128.

Use the drop-down menus to complete the explanation about how Skyla can use her graph to solve the equation 2x = 128.

Skyla looks for the x-value at which the graph of the function 2^x intersects the horizontal line defined by the constant function: f(x)=128

Step-by-step explanation:

Look for an answer that involves something like:

By looking for the point where both functions intersect, Skyla can find for which x value the following equation is verified: 2^x=128

She must read at which x-value the intersection occurs, and that is the answer.
