Arionna needed to graph triangle PQR reflected across the y-axis. Her work is shown below. Arionna’s Work: Blue right-arrow red.

P (3,7) right arrow P prime (3, negative 7). Q (0, 4) right-arrow Q prime (0, 4). R (5, 8) right-arrow R prime (negative 5, 8). Arionna’s Graph On a coordinate plane, a red triangle has points (negative 7, 3), (negative 5, 8), (0, 4). A blue triangle has points (0, 4), (3, 7), (5, 8). Which statements identify her errors? Check all that apply. Arionna did not find the correct point for P’. She should have negated the x-value, not the y-value. Arionna did not find the correct value for Q’. All points in a reflection will move. Arionna did not find the correct value for R’. She should have negated the y-value, not the x-value. Arionna’s red triangle should be reflected below the horizontal axis rather than across the vertical axis. Arionna switched the order of the coordinates of P’ (3, –7) when she graphed them.

The one-to-one functions g and h are defined as follows
Debora [2.8K]

Answer:

g^-^1(x)=-8

h^-^1(x)=\frac{x-4}{3}

(h^-^1 \ o\ h)(-3)=-3

Step-by-step explanation:

When given the following functions,

g=[(-2,-7),(4,6),(6,-8),(7,4)]

h(x)=3x+4

One is asked to find the following,

1. Question 1

g^-^1(4)

When finding the inverse of a function that is composed of defined points, one substitutes the input given into the function, then finds the output. After doing so, one must substitute the output into the function, and find its output. Thus, finding the inverse of the given input;

g^-^1(4)

g(4)=6\\g(6)=-8\\g^-^1(4)=-8

2. Question 2

h^-^1(x)

Finding the inverse of a continuous function is essentially finding the opposite of the function. An easy trick to do so is to treat the evaluator (h(x)) like another variable. Solve the equation for (x) in terms of (h(x)). Then rewrite the equation in inverse function notation,

h(x)=3x+4\\\\h(x)-4=3x\\\\\frac{h(x)-4}{3}=x\\\\\frac{x-4}{3}=h^-^1(x)

h^-^1(x)=\frac{x-4}{3}

3. Question 3

(h^-^1 \ o\ h)(-3)

This question essentially asks one to find the composition of the function. In essence, substitute function (h) into function (h^-^1) and simplify. Then substitute (-3) into the result.

h^-^1\ o\ h

\frac{(3x+4)-4}{3}\\\\=\frac{3x+4-4}{3}\\\\=\frac{3x}{3}\\\\=x

Now substitute (-3) in place of (x),

=-3
