Answer:
Inverse of a function
Step-by-step explanation:
If the x- and y-values in each pair of a set of ordered pairs are interchanged, the resulting set of ordered pairs is known as the inverse of a function.
For example, given the following function:
y = 2x
If x=0 → y= 0
If x=1 → y= 2
If x=2 → y= 4
Now, if we find the inverse of the function:
y = 2x → x = 2y → y = x/2
Now:
If x=0 → y= 0
If x=2 → y= 1
If x=4 → y= 2
Comparing both cases, you will notice that the ordered pairs are effectively interchanged.
Answer:
2/3 × 9/5 = 18/15 = 6/5 if need to simplify. or 1 1/5
Step-by-step explanation:
Answer:
21 in.
Step-by-step explanation:
The radius is half of the diameter. The diameter (as shown) is 42 inches. Divide that by two to get 21 in.
Answer:
3/-1
Step-by-step explanation:
The slope is 3/-1 (Rise 3 on the y axis, run to the negatives by 1 on the x axis)
To find the slope of two points, use the formula of y2-y1/x2-x1 (For example, with this equation it would be 10-4/10-12)
I'm not sure what it means to interpret the slope, but hopefully this helped you!
