Answer: yes, because it is useful to describe changes in the behavior of the thing we are describing.
Step-by-step explanation:
A piecewise function f(x) is a function that is "different" depending on the range of the values of x, this is for example:
y = x -----> if x < 0
y = x^2 ----- if x ≥ 0
This is used to represent changes in the behavior of the thing we are describing.
For example, suppose an object that is moving with constant velocity, the velocity graph will be a constant line.
Now, the object suddenly, at a time t = t0 accelerates to a constant acceleration A, now the graph of the velocity is a linear graph with slope equal to A.
So this situation can be represent this with a piecewise function:
V(t) = c -----> if t < t0
V(t) = c + A*t -----> if t ≥ t0
So the answer is yes, we can.
Answer:
j
Step-by-step explanation:
hey, wait a second... I saw you earlier, are you just putting all the questions on your math test here so you dont have to any of the work?
that's pretty smart.
measure of what you have not finished the question
12w-27 = -34+14w
We need to keep variables on one side and constant on other side . Here variables are 12w and 14w and constants are -27 and -34 .
So we need to move -34 to left side and 12 w to right side . And for that, we need to add 34 to both sides and subtract 12 w to both sides.
12w-27+34-12w=-34+14w+34-12w
7= 2w
Now we need to get rid of 2. So we divide both sides by 2 , and on doing that, we will get
