Answer:
Function - Yes
Domain - [-3,0,3,4]
Range - [1,2,2,5]
Step-by-step explanation:
In a function, x-values cannot repeat and in this relation, x's do not repeat, therefore it is a function. The domain is the x-values on the graph from least to greatest; so to find the domain, simply take the first value of each coordinate and order them from least to greatest. Then, the range is the y-values, so to find the range take the second value from each coordinate and order them from least to greatest.
The linear equation in slope-intercept form can be written as:
y = 5*x + 6
<h3>How to find the linear equation?</h3>
A general linear equation in the slope-intercept form is:
y = a*x + b
Where x is the independent variable, y is the dependent variable, and a and b are constant real numbers, such that a is the slope and b is the y-intercept.
Here we know that the slope is 5, then we can replace a by 5.
And we know that the y-intercept is (0, 6), it means that b = 6.
Then the linear equation in slope-intercept form can be written as:
y = 5*x + 6

To solve this we are going to use the kinematic equation for final velocity:
where
is the final velocity
is the initial velocity
is the acceleration
is the time
We know for our problem that the the velocity at the beginning of the slope is
, so
. We also know that the speed ad the bottom of the slope is
, so
. We also know that the acceleration is
, so
. Lets replace those values in our formula and solve for
:
seconds
We can conclude that it takes the roller coaster
3 seconds to reach the bottom of the slope.
