1] Temperature over the course of an afternoon
This is because graph of typical step function are always plotted in such a way that there is an independent variable which defines the outcome of a dependent one, temperature is not dependent on any factor, it is a random occurrence.
Answer: d] Temperature over the course of an afternoon
2] Discontinuous points are those points which are not defined. From the graph, the number of discontinuous points are 4.
Answer: 1] 4
3]The rate of increase of the function between 10 and 15?
rate of change=(change in y-values)/(change in x-axis)
using point (10,0) and (15,0)
=(0-0)/(15-10)=(0/15)=0
Answer [2] 0
4] a] Stacey Johnson earned $50,825 in 2005, how much was her income tax?
Amount of $50825 is between the income range of $50800 and 50, 900. Thus the tax deductions will be: $3570

rate=(tax paid)/(income earned)
rate=3570/50825

c] Her brother, Thomas paid $3510 in taxes, Express his income as an inequality.
The range of tax of $3510 is:
50,400≤x≤50,500
Answer:
2. (-3f)
3. (4f)
4. x - 11 (not sure if this one is correct)
Step-by-step explanation:
Move -3 to the left of f = -3f
Move 4 to the left of f = 4f
f(x)=x+11 f ( x ) = x + 11
Answer:
102
Step-by-step explanation:
These angles are congruent due to corresponding angles thm
3x + 21 = 6x - 60
3x - 6x = -60 - 21
-3x = -81
x = 27
3x + 21
3(27) + 21
81 + 21
102
