Answer:
Exponential function.
Step-by-step explanation:
We are given that a function of the form
Where 
and b>0
Exponential function: The function is of the form
Where b is a positive constant and greater than 0 and x is any real number.
The given function satisfied the define of exponential function.
Hence, the function of the form
Where b>0 and are called exponential function.
Yes they are so similar cause one is the image and the other one is the pre-image
Answer:
8 Vans & 7 buses.
Step-by-step explanation:
<u>Given: </u>
Total number of students = 231
1 van rode = 7 students
1 bus rode = 25 students
Let x denote the number of vans used & y denote the number of bus used, then,
x+y = 15 ........(1)
and, 7x + 25y = 231.....(2)
<u>On solving eq(1) & (2) we get, </u>
From equation (1), x = 15-y
Putting in eq(2), we get,
7(15-y) + 25y = 231
105 - 7y + 25y = 231
18y = 126
y = 7
and, x = 15 - 7 = 8
<u>Hence, 8 vans were used & 7 buses were used.</u>
