Answer: f-1(y) = (y-3)/2
Step-by-step explanation:
f(x) = 2x+3, written as a flow diagram:
2x+3
The Inverse Function goes the other way:
Inverse
So the inverse of: 2x+3 is: (y-3)/2
The inverse is usually shown by putting a little "-1" after the function name, like this:
f-1(y)
We say "f inverse of y"
So, the inverse of f(x) = 2x+3 is written:
f-1(y) = (y-3)/2
Answer:
base = 5.6 cm
Step-by-step explanation:
area of a triangle = 1/2 * base * height
area = 5.88 cm²
height = 2.1 cm
5.88 = 1/2 * base * 2.1
5.88 = 1.05 base
5.88 / 1.05 = base
base = 5.6 cm
Answer:
36% loss
Step-by-step explanation:
To calculate percentage loss
