Design A Roller Coaster Portfolio

Further explanation

Fix A to set up B is said to be a part if each fellow member of set A pairs is exactly ane member of set B

And then, i value of 10 is only assigned to ane value of y

If y is a function of x, so y = f (10)

Charge per unit of Change part shows the comparison between two objects that alter

If we utilise the annotation function, the rate of Alter from a part from a to b can be formulated as:

$\large {\boxed {\boxed {\bold {ROC = \frac {f (a) -f (b)} {a-b}}}}$

ROC = rate of change

the domain and range of this roller coaster

The Domain is the X values, 0-360

written as (0,360)

The range is the Y values, 0-250

written as (0,250)

2. a. The slope of the initial climb

from points 0,0 and 70,250

slope = 250/70 = iii.57

b. equation from bespeak 70,250

y-y1 = m (x-x1)

y-250 = 25/vii (x-70)

y = 25 / 7x-250 + 250

y = 25 / 7x

3. rate of change from (200, 200) to (300, 60) --- green hill

ROC = 60-200 / 300-200

ROC = -140/100

ROC = -1.4

4. rate of change from (200, 230) to (60, 30) - bluish hill

ROC = xxx-230 / sixty-200

ROC = -200 / -140

ROC = ane.42

v. The greater the slope, the steeper the line

the blue colina is steeper than the green loma because the gradient value of the blue loma is greater (steepness is not determined from the negative slope value)

6.the roller coaster is not a function, because in that location are 2 domain values that are paired with the codomain for case points 200,200 and 200,230
