Step-by-step explanation:
a) Mapping the graphs
Mapping one graph (A) onto another (B) means that each vertical line through a point in A intersects the graph of the B at only one point.
In the diagram, the graph of ƒ(x) = √(x² + 9) is the blue line and the graph of g(x) = 5 + √(x² + 9) is in green.
Each vertical line through ƒ(x) intersects g(x) in only one point.
For example, a vertical line from (4, 0) intersects ƒ(x) at (4, 5) and g(x)
at (4, 10).
Every point in g(x) is five units higher than the corresponding point in ƒ(x).
Thus, mapping ƒ(x) onto g(x) is a translation of five units upward.
b) Integration
Answer:
A = m²
Step-by-step explanation:
Given that a square has a perimeter of (2x - 48),
Each side of the perimeter must be: (because a square has 4 sides)
We need to determine the side of each perimeter:
s =
Factor out 2 from the numerator:
s =
Then, cancel out 2 and 4 from the fraction, leaving 2 in the denominator:
s = ← <em><u>This represents the side of a square</u></em>
Therefore, the area of a square is:
A = side (s)²
A = m²
