Answer: +9,+5
Step-by-step explanation:
To find the inverse function of a function, you rearrange for the x term (could be some other letter) and then swap the function and the x at the end. For example,
and so,
For part 3 we have
and hence,
Can you do part 4 on your own?
Answer:
Dividing by 4 and -4
Step-by-step explanation:
Solving 4x < -16 is different from solving -4x< 16, because for 4x < -16, you are dividing by a positive 4 on both sides, but for -4x< 16, you are dividing by -4 on both sides.
