Answer:
see the explanation
Step-by-step explanation:
we know that
The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity
In this problem we have
This is a vertical parabola open upward
The vertex is a minimum
so
as x approaches positive infinity ----> the value of g(x) approaches positive infinity
as x approaches negative infinity ----> the value of g(x) approaches positive infinity
f(x)→+∞, as x→−∞
f(x)→+∞, as x→+∞
see the attached figure to better understand the problem
Answer: Hours by Tina practiced this month is 3 times the hours she practiced last month such that 15 x 3 =45 hours.
Step-by-step explanation:
Given : Duration of Tina practiced piano last month= 15 hours
Duration of Tina practiced piano this month= 45 hours
We can see 45 is a multiple of 15 such that
Therefore, Hours by Tina practiced this month is 3 times the hours she practiced last month such that 15 x 3= 45 hours.
