second-period class average:

55+70+450+480+170+270+95 = 1590

1590/20 = 79.5

sixth-period class average:

65+225+480+595+270+190 = 1825

1825/20 = 91.25

on average, students in the sixth period class scored higher

Can we combine different functions (quadratic, linear, exponential, cube root) into one piecewise function? If the answer is yes
yanalaym [24]

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.
