Remark
What the question is saying is that you are setting up a proportion. Ordinarily a child would require 125 mg be put into 5 mL of liquid. This child is special and only requires 100 mg. How many mL are needed?
Proportion
125 mg : 5 mL :: 100 mg: x
Solution
125 / 5 = 100 / x Cross multiply
125x = 500 Divide by 125
125x/125 = 500/125 Do the division
x = 4
Answer
100 mg would be put in 4 mL of liquid
Consider the bottom most rectangle.
Its length = 5 - 2 = 3 units
Its width = 3 - 1 = 2 units
So, its area = 3(2) = 6 square units.
Consider the middle rectangle.
Its length = 2 - 1 = 1 unit
Its width = 4 - 2 = 2 units
So, its area = 1(2) = 2 square units.
Finally, consider the top rectangle.
Its length = 6 - 1 = 5 units
Its width = 6 - 4 = 2 units
Its area = 5(2) = 10 square units.
Hence, total area = 6 + 2 + 10 = 18 square units. Correct option is C.
1) f(0) means to find y value when x= 0
x=0, y=2, so f(0) =2
2) f(x) = 0
y=0,x=?
When y=0, x=4
3) f⁻¹(0),
This is an inverse function of f(x),
that means that for f⁻¹, that values of x become y, and values of y become x.
f⁻¹(0)
"0" is y from the graph, when y=0, x=4, so
y=0, f⁻¹(0) = 4
4) f⁻¹(x)=0,
means that on this graph we need x=0, y=2,
so f⁻¹(2)=0,
x=0
For function we had
x=0, y=2
x=4, y=0
For f⁻¹ inverse function we have (x becomes y, and y becomes x)
x=2, y=0
x=0, y=4
