Answer:
D
Step-by-step explanation:
First let's notice a couple things:
- All the answers are in y = mx + b form
- Two of the answers don't have a value for b
- Pretty much all of the answers have a different m value
So let's go in order of our realizations.
Let's start with figuring out what b is. By simply looking at the graph, we can see that b = 0, because the line starts at (0, 0). Remember that b is when the line crosses the y axis, and our y value at x = 0 is 0.
This crosses out A and B.
Now let's find m, aka the slope. We can figure this out using the slope formula:
Awesome! So we've figured out that m = 7/2. This means our answer has to be D.
Answer:
- The range of the given function is [6, + ∞)
Step-by-step explanation:
It is assumed the function is:
We know the square root is non-negative, so:
- x - 8 ≥ 0 therefore the function gets values
- f(x) ≥ 0 + 6
- f(x) ≥ 6
We can show this as:
- f(x) ∈ [6, + ∞)
Step-by-step explanation:
The frequency of sine function is given by the number of periods in a given range. For example:
- Frequency for
is 1 in the interval
.
This means that, if we want another sine function with frequency 20% higher, we need that function to have a frequency of 1.2 in the interval .
To be easier to see we will consider interval instead of
. In this interval
has 5 periods, therefore our new sine function should have 6 periods.
Finally, as we can see in the graph, the function (in blue) has a frequency 20% higher than
(in red). This can be easily seen counting the number of periods between 0 and
for both functions. 5 for
and 6 for
.
