Option a is not a function because for x = 0, y = 3 and 4.
option b is a function.
option c is not a function because for x = 2, y = 1 and 8.
option d is not a function because for x = 1, y = -3 and 4
Answer:
71663616
Step-by-step explanation:
3 x 3 x 3 x3 x 3 x3 x 3 = 2187
8 x 8 x 8 x 8 x 8 = 32768
2187 x 32768= 71663616
For both its 47.58 for low one its 22.68 and high 24.90
Answer:
The minimum value of y is -7
Step-by-step explanation:
Given: 
We are given a cosine function.
We need to find minimum value of function.

Here y is depends on cosine function.
y is minimum when cosine is minimum because y is directly proportional to cosine function.
Minimum value of cos x is -1
Therefore, For minium value of y

Minimum value of y


Hence, The minimum value of y is -7
Answer:
Step-by-step explanation:
perp. 5/2
y - 1 = 5/2(x - 2)
y - 1 = 5/2x - 5
y = 5/2x - 4
