Im practicing for my test on Monday, I don't quite get how to do this question
I tried to make everything same base but that didnt work, combining the 3 base was also quite strange

$$y_2 - y_1 = 24+3^{x}-3^{x+2} = 24 + 3^x \left(1-3^2\right)$$ Now at the intersection point, $y_2 = y_1$ giving, $$24 + 3^x \left(1-3^2\right) = 0$$ This should be straightforward. You should always try combining the exponential parts or unknown parts of an equation whenever you see something like this.
