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?

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

5x+2x=49

7x=49

x=7. 35 apples

the square root of what number? if you add that, then someone will probably answer the question.
