Answer:
1 to 1
Step-by-step explanation:
function f in more than one point, then the function is 1 to 1
3 to the 1st is 3
3 to the 2nd is 9
3 to the 3rd is 27
3 to the 4th is 81
3 to the 5th is 243
3 to the 6th is 729
First, find the 40% discount.
40% of 195 is 78
195 x 0.40 = 78
Subtract that from 195
195 - 78 = 117
Now, find 66 2/3% of 117, since it is an additional reduction after the original discount.
2/3 = 0.667, so 66 2/3% is 66.667%
117 x 0.66667 = 78.00039
And subtract that from 117
117 - 78.00039 = 38.99961, which in dollars would be $38.99. (hundredths, etc. of a cent are usually just dropped; no rounding involved.)
The discount price would then be $38.99
50:
40 is 10 less than 50
60 is 10 more than 50
Well, I suppose you could break up the coordinate plane
in millions of different ways.
If you take each region to be all the space that is not crossed
by an axis, then you have the four Quadrants.
