Answer:
No maximum
Step-by-step explanation:
Given
Solving (a): The minimum
The minimum is when the absolute parameter gives 0
i.e.
Divide both sides by 0.9
Open bracket
Remove absolute sign
Collect like terms
Then the y value is:
Recall that:
So, we have:
Hence, the minimum is at:
Since the minimum is at , then the graph will open upwards.
Hence. the function has no maximum; i.e.
