The figure which is rotated and translated correctly about the x-axis is figure a.
The graph of a function f is that the set of ordered pairs, where\f(x)=y. within the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
We have been given four graphs of a function and first function has coordinates (-5,7) (-2,6) (-7,4) (-4,1) and that we must identify correct reflected graph.
The coordinates of a pure reflected graph are going to be (4,7) (2,4) (5,1) (7,6) which are the coordinates of figure a which is in first quadrant.
Hence the proper reflected graph of function having coordinates (-5,7) (-2,6) (-7,4) (-4,1) is that the graph of coordinates (4,7) (2,4) (5,1) (7,6).

Answers:
Figure a has been translated only (translated 9 units to the right)
Figure b has been reflected over the x axis
Figure c has been rotated and translated
=======================================
Explanation:
Pick on a point like (-7,4) and note how it moves 9 units to the right to get to (2,4). All points on the upper left figure follow this same translation rule. This rules in figure a.
Figure b is a result of reflecting over the x axis. The rule used is . The x coordinate stays the same while the y coordinate flips from positive to negative. So for example, (-7,4) flips to (-7,-4)
Figure c is a combination of rotating and translating the original figure. It looks like a 90 counterclockwise rotation has been applied followed by a translation. The actual translation and rotation rules used will depend on how you define the center of rotation.
The number of hours Tom took a trip of 1,020 miles is 3 hours.
Given that, Tom took a trip of 1,020 miles.
The speedformula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.
Tom traveled by train at 55 miles an hour and the same number of hours by plane at 285 mph.
Let the number of miles travelled by train be x. Then, the number of miles travelled by plane be 1020-x.
Time = x/55 = (1020-x)/285
⇒ 285x = 55 (1020-x)
⇒ 285x = 56100 - 55x
⇒ 285x + 55x = 56100
⇒ 340x= 56100
⇒ x = 56100/340
⇒ x = 165 miles
So, time = 165/55 = 3 hours
Therefore, the number of hours Tom took a trip of 1,020 miles is 3 hours.

Step-by-step explanation:
The value of f^-1(3) is 4
The inverse of a function f(x) is the opposite of the function
The functionf(x)is given as:
Express f(x) as y
Swap the positionsof x and y
Express as exponents
Make y the subject
Express the equationsas an inverse function
Substitute 3 for x in the above equation
Evaluate
Hence, the value of f^-1(3) is 4
