7% of 340
Note: "of" means multiplication
7% x 340 = .07 x 340 = 23.8
Answer: amount of sales tax is $23.80
As the intervals moves from left to right on the graph, the average rate of change increases
<h3>How to determine the change in the rate of change?</h3>
The function is an exponential growth function.
This is known because it has an initial value at (0, 2), and the value increases to the right
The average rate of change of exponential growth functions increases towards the right.
This means that:
The initial statement is "as the intervals moves from left to right on the graph, the average rate of change increases
Because the average rate of change keeps changing, the final statement is:
Since the average rate of change is also changing, the function is changing and approaches infinity

Answer:
yes
Step-by-step explanation:
since its more than 90 dgree
Answer:
The graph of y = f(-x) is a reflection of the graph of y = f(x) in the x-axis. ⇒ False
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the y-axis. ⇒ False
Step-by-step explanation:
<em>Let us explain the reflection about the axes</em>
- If a graph is reflected about the x-axis, then the y-coordinates of all points on it will opposite in sign
Ex: if a point (2, -3) is on the graph of f(x), and f(x) is reflected about the x-axis, then the point will change to (2, 3)
- That means reflection about the x-axis change the sign of y
- y = f(x) → reflection about x-axis → y = -f(x)
- If a graph is reflected about the y-axis, then the x-coordinates of all points on it will opposite in sign
Ex: if a point (-2, -5) is on the graph of f(x), and f(x) is reflected about the y-axis, then the point will change to (2, -5)
- That means reflection about the y-axis change the sign of x
- y = f(x) → reflection about y-axis → y = f(-x)
<em>Now let us answer our question</em>
The graph of y = f(-x) is a reflection of the graph of y = f(x) in the x-axis.
It is False because reflection about x-axis change sign of y
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the x-axis
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the y-axis.
It is False because reflection about y-axis change sign of x
The graph of y = f(-x) is a reflection of the graph of y = f(x) in the y-axis
