Which statement best describes the effect on the graph of y = (x – 9)2 if the equation is changed to y = (x + 9)2? The graph mov

Answer:

Third option: The graph moves left 18 units.

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

If $f(x)+k$ , the function is shifted up "k" units.

If $f(x)-k$ , the function is shifted down "k" units.

If $f(x+k)$ , the function is shifted left "k" units.

If $f(x-k)$ , the function is shifted right "k" units.

In this case, we can observe that graph of $y = (x - 9)^2$ is changed to $y = (x + 9)^2$

Since:

$-9+18=9$

We can conclude that the function $y = (x - 9)^2$ is shifted left 18 units to get the function $y = (x + 9)^2$ .

Arrange these numbers from least to greatest:

zmey [24]

First let's put them all over 100.
- $\frac{5}{8}$ would change to - $\frac{62.5}{100}$

- $\frac{7}{9}$ to - $\frac{77.7}{100}$

- $\frac{4}{5}$ to - $\frac{80}{100}$

- $\frac{3}{7}$ to - $\frac{42.8}{100}$

Then if we put them from least to greatest it would be from highest to lowest (since they are negatives)

- $\frac{4}{5}$ , - $\frac{7}{9}$ , - $\frac{5}{8}$ , - $\frac{3}{7}$

The answer would be B
