Question

Help I have no idea how to solve this?!
Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 8^x and y = 2^(x + 2) intersect are the solutions of the equation 8^x = 2^(x + 2). (4 points)
For this part I graphed the equations and the point of intersection is (1,8) But Im so confused I'm not even sure what they are asking.

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

Part C: How can you solve the equation 8^x = 2^(x + 2) graphically? (2 points)

Answer 1

at the point where they intersect the values of x and y will satisfy both equations because that point s on both the graphs of the 2 equations.

Answer 2

* point is

Answer 3

So that would be Part A? So for Part B would you create a normal table and plug in the values?

Answer 4

Answer 5

for value of x -3,-2,-1 0 1,2,3
work out the values of y for both equations.

then draw a 2 column table listing values of x and y's.

Answer 6

@welshfella this is what i got
