Answer:
22 games
Step-by-step explanation:
From the barchart :
We can obtain the total number of goals scored :
Home goals (quarter 1 to quarter 4) :
= (9 + 6 + 8 + 7) = 30
Away goals (quarter 1 to quarter 4) :
= (2 + 7 + 4 + 5) = 18
Using the relation :
Mean goals scored = total goals scored / number of games played
Home games :
Mean goals = 2.5
Number of home games played = total goals / mean goals scored
= 30 / 2.5
= 22
Away games :
Mean goals = 1.8
Number of away games played = 18 / 1.8
= 10
Number of home and away games played in total = 22 + 10 = 32 games
The required inverse function = (2x - 3 ) / 4.
Given that,
f(x) = (2x+3) / 2
To find
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Let f(x) = y
y = (2x + 3) / 2
y * 2 = 2x + 3
2y - 3 = 2x
x = (2y - 3) / 2
Now replace y = x and x =
= (2x - 3 ) / 4
Thus, the required inverse function = (2x - 3 ) / 4.
