Answer:
A -- the curves that are not parabolas
Step-by-step explanation:
The inverse relation will only be a function if it passes the vertical line test: a vertical line cannot intersect the curve at more than one point.
A "half-parabola" can have an inverse function.
A parabola will have an inverse relation that is not a function. When x-values are repeated, as "goes through (5, 2) and goes through (5, -2)", the relation is not a function.
The graph that shows inverse functions is attached. A function and its inverse are mirror images of each other in the line y=x.

Answer:
The coordinates of L is (11, 5)
Step-by-step explanation:
<u>Points to remember</u>
Let (x1, y1) and (x2, y2) be the points and P (x, y) be the points in which its divide the line segment in the ratio p : q,the coordinates of P is given by,
x = x1 + p/(w)(x2 - x1)
y = y1 + p/w(y2 - y1)
Where w = p + q
<u>To find the coordinates of L(x, y)</u>
Here, (x1, y1) = N(14, 4) and (x2, y2) = M(2, 8)
p = 1 and w = 1+3 = 4
x = x1 + p/(w)(x2 - x1)
= 14 + (1/4)(2 - 14)
= 14 + -3 = 11
y = y1 + p/w(y2 - y1)
= 4 + (1/4)(8 - 4)
= 4 + 1 = 5
Therefore the coordinates of L is (11, 5)
Simplify 3.8x + 5.2x - 6.7 to 9x - 6.7
9x - 6.7 = 11.3
Add 6.7 to both sides
9x = 11.3 + 6.7
Simplify 11.3 + 6.7 to 18
9x = 18
Divide both sides by 9
x = 18/9
Simplify 18/9 to 2
<u>x = 2</u>
