Answer:
C
Step-by-step explanation:
f(x) = Price
2.00 = Price of one ride
x = number of times ridden
f(x) = 2x
The function is :
y = √(x-12), x≥12
To find the inverse function, we interchange x and y, and then make y the subject again.
So interchanging x and y we have:
x = √(y-12)
Squaring both sides gives;
x² = y-12
Now making y the subject we have,
y = x² +12
x≥0.
Therefore the inverse function is;
y = x² +12, x≥0.
Hence the correct answer is C.
20/100
= 0.2
0.2 x 20
= 4
4 of the shops are ice cream shops.
