2x2 + 9x – 7
Step-by-step explanation:
Answer:
Option (C).
Step-by-step explanation:
In the graph attached,
An absolute function has been given.
To check a graph whether it's a relation or a function, vertical line test is a trusted tool.
In vertical line test a vertical line (parallel to y-axis) is drawn passing through the graph.
If the vertical line cuts the graph at only one point then the graph is said to be a function.
The given graph passes the vertical test.
Therefore, it's a function.
Option C. will be the answer.
Tan 18 = x/2
⇒ 0.3249 = x/2
⇒ x = 2 * 0.3249 =
⇒ x = 0.6498 ≈ 0.65
Hope it helps!
