Firstly the coefficient, or the number next to the variable, which is x, goes before it. So instead of x3, it's 3x.

So, to solve to find what x is, you need to divide by 3 on both sides of the equal sign.

3x=729

Dividing by 3 on the left cancels out the 3, leaving just the x.

Dividing the other side gets you what x equals.

x= 243

Describe the transformation from the parent function y=(x+4)^2-1

Degger [83]

Answer:

Translation 4 units to the left., followed by

a translation 1 unit down.

Step-by-step explanation:

The parent function is y = x^2 which is a parabola that opens upwards and has a vertex at the point (0,0).

Y = (x + 4)^2 is the graph of x^2 translated 4 units to the left.

The - 1 translates the graph down 1 unit.

So the vertex of the new graph is at (-4, 1).

Which of the following describes the transformations of g (x) = negative (2) Superscript x + 4 Baseline minus 2 from the parent

o-na [289]

Answer: First option.

Step-by-step explanation:

Below are some transformations for a function $f(x)$ :

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

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

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

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

5. If $-f(x)$ , the function is reflected over the x-axis.

6. If $f(-x)$ , the function is reflected over the y-axis.

Then, given the parent function $f(x)$ :

$f(x)=2^x$

And knowing that the the other function is:

$g(x)=-2^{(x+4)}-2$

You can identify that the function $g(x)$ is obtained by:

- Shifting the function $f(x)$ 4 units left.

- Reflecting the function $f(x)$ 4 over the x-axis.

- Shifting the function $f(x)$ 2 units down.
