Answer:
the y-intercept of this function is -2 or (0, -2)
Step-by-step explanation:
B. Step 3 is incorrect, it should be x = 10/8
The only zero of is .
The function is the inverse of function .
For a given and a given , if and only if .
Let be a zero of . That is, .
By the reasoning above, since and this particular satisfy , it must be true that for the same and .
Since and , . Therefore, since .
Thus, the zero of would be .
