Answer:
x tan q
Step-by-step explanation:
Refer the attached figure
An observer on the ground is x meters from the base of the launch pad of a rocket i.e. BC = x
The height of the rocket is AB
The observer sees its tip at an angle of q° from the horizontal.i.e.∠ACB = q°
In ΔABC
We will use trigonometric ratio
So, the height of the rocket is x tan q.
So, Option C is correct.
Hence the tip of the rocket is x tan q far above the ground
Given:
The graph of a parabola.
To find:
The domain, range and check whether it is a function or not.
Solution:
Domain: The set of x-values or input values is known as domain.
Range: The set of y-values or output values is known as range.
A relation is a function if their exist unique outputs for each input. In other words a graph is a relation if it pass the vertical line test.
Vertical line test: Each vertical line intersect the graph at most once.
The given function is defined for all real values of x which are greater than or equal to -3. So, the domain of the given graph is:
The given function values can be any real number. So, the range of the given graph is:
For x=0, we have two values of the function because the graph intercept the y-axis at two points.
Since the graph does not pass the vertical line test therefore the given graph is not a function.
