This is an example of a piecewise defined function. It means that the function has not a unique formula to represent it, but it depends on "where" you want to compute it.

So, if you choose any input x, you have two alternative:

  • If x \neq 3 (i.e., if you've chosen any input that is not 3), the output will be the opposite of the input you've chosen (y=-x)
  • If x=3, the ouput will be -1.

So, let's forget about x=3 for a moment. For any input x you choose, the answer is -x. The graph of this function is the bisector of the second and fourth quadrant.

Now remember that there is our special case: you have to "carve a hole" in our line, at x=3, and assing to this point the value -1, instead of what we would expect, i.e. -3.

So, the graph of this function is the line y=-x, except for one point (x=3), where we reassign the value to be -1.

Answer:

1

Step-by-step explanation:

One.  For example, if we chose 5 as the number, then the multiplicative inverse would be 1/5.  Multiplying 5 by 1/5 results in one (1).

On a trip, a motorist drove 150 miles in the morning and 50 miles in the afternoon. His average rate in the morning was twice hi
Lina20 [59]

Answer:

Morning's average rate = 50 mph, and Afternoon's average rate = 25 mph.

Step-by-step explanation:

Suppose he drove 150 miles for X hours, then his average rate in the morning was (150/X) mph.

Given that he spent 5 hours in driving.

And he drove 50 miles for (5-X) hours, then his average rate in the afternoon was 50/(5-X) mph.

Given that his average rate in the morning was twice his average rate in the afternoon.

(150/x) = 2 * 50/(5-x)

150/x = 100/(5-x)

Cross multiplying terms, we get:-

150*(5-x) = 100*x

750 - 150x = 100x

750 = 100x + 150x

750 = 250x

x = 750/250 = 3.

It means he spent 3 hours in the morning and 2 hours in the afternoon.

So morning's average rate = 150/3 = 50 mph.

and afternoon's average rate = 50/(5-3) = 25 mph.
