PLEASE HELP!!

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 2^−x and y = 8^x+4 intersect are the solutions of the equation 2^−x = 8^x+4.

Part B: Make tables to find the solution to 2^−x = 8^x+4. Take the integer values of x between −3 and 3.

Part C: How can you solve the equation 2^−x = 8^x+4 graphically?

Answer:

Part A: They intersect at 2^−x = 8^x+4 since the two graphs are equal therefore they give out the points where they meet / intersect.

Part B:

when x = -3

8 = 1/512 + 4 False

when x = -2

4 = 1/64 + 4 Closest

x ≈ -2

Part C:

Plot 2^-x

Plot 8^x + 4

Find the intersection points on the graph
