Answer:
- vertical stretch: the function value (f) is multiplied by the stretch factor
- horizontal stretch: the variable (x) is divided by the stretch factor
Step-by-step explanation:
A stretch can be vertical, horizontal, or both.
Multiplying the function value by a factor greater than 1 will stretch the graph vertically.
Dividing the variable value by a factor greater than 1 will stretch the graph horizontally.
__
The graph is stretched by the factor according to how it is applied.
Y= Slope(x) + y-int.
Y= mx +b
Y= -3x +2
Answer:
sali's speed was 18.75 km/h
Step-by-step explanation:
Jane took 3.5 hours to cycle the 63 km.
As, , so the speed of Jane will be:
Suppose, the speed of Sali is km/h
Sali caught up with Jane when they had both cycled 30 km.
So, the time required for Jane to cycle 30 km and the time required for Sali to cycle 30 km
Given that, Sali started to cycle 4 minutes or after Jane started to cycle. So, the equation will be.......
