You need to remember that the graph of function intercepts x axis at y=0, hence f(x)=y=0.
You need to solve the equation `2^x - 2= 0` .
I suggest to you to isolate the term containing x to the left side, hence:
`2^x = 2`
Since the base are alike you may equate the exponents such that:
x = 1
Hence, the graph intercepts x axis at the point (1,0).
You need to remember that the graph intercepts y axis at x = 0, hence, you need to substitute 0 for x in the equation of function such that `f(0) = 2^0- 2 = -1.`
Hence, the graph intercepts y axis at the point (0,-1).
The image below represents the graph intercepts to x axis and y axis.
Hence, the graph intercepts x axis at the point (1,0) and it intercepts y axis at the point (0,-1).
