A though without graphing software it would appear to be C

Step-by-step explanation:
The inverse of a function is the function reflected across the line y=x. This results in the coordinate points (x,y) of the function becoming (y,x) for the inverse function. Algebraically to find the inverse, switch the x and y locations and solve for y.
y = 7x^9
x = 7y^9
x/7 = y^9
(9)√(x/7) = y
This is a ninth root of (x/7) also written in exponents as y = (x/7)^(1/9).
This is a function. While it appears not to be a function because the middle portion over the origin appears vertical, it is a function because the middle portion over the origin is changing and graphing software shows it has no input with more than one output. Without graphing software you would rule it is not a function.

problem: report error when the measures of the angles of a triangle are placed in order, the difference between the middle angle

laiz [17]

The triangle's biggest angle's measurement in degrees is 97°.

What is a triangle?

A triangle is a polygon with three vertices and three sides. The angles of such a triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
All of the angles in an acute triangle are below 90 degrees.
Any angle in an obtuse triangle is larger than 90 degrees.
There is just one 90-degree angle in a right triangle.

Let $a+b+c=180$ ° with $a < b < c$
