Answer:
y=0.3x
Step-by-step explanation:
Formula =
y α x
y = kx
Where k is the constant of proportionality.
When y = 1.5; x = 5;
We substitute these known values in the equation,
y = kx
1.5 = k5
Dividing both sides of the equation by 5 to find the value for k, we have
1.5/5= k0.3/5
Therefore,
K = 0.3
Having found the value of k,
We substitute this value into the relationship
y = kx
Therefore we have,
y = 0.3x.
The direct variation function is therefore,
y = 0.3x.

Step-by-step explanation:
Do you mean or
?
Use the formula where
is the amplitude,
is the phase shift,
is the vertical shift, and the period is
.
Assuming your first case is true, the amplitude would be , your period is
, and your midline/vertical shift is
.
Assuming your second case is true, everything but the vertical shift stays the same. It would be in this case.
