Answer:
A, C, and F are functions.
Step-by-step explanation:
Since we are given that the relationship between x and y
is linear. Therefore this means that the given equation takes the form of:
y = m x + b
where,
b is the y intercept of the equation
m is the slope of the equation
However we should take note that the slope m is directly
proportional to the coefficient of correlation. Since our coefficient of
correlation is negative, this only means that the value of y is decreasing with
increasing x, hence plot of y and x is descending with increasing x.
Furthermore, this also tells that for every 1 unit increase of x, there is a
0.75 units decrease of y.
Negative since the answer would be -13
The multiple zero is x = -4.
The multiplicity is 2 because there are two values of x.
Your answer is: 3. 3 hours, 18 minutes
