Which equation describes the graphed function?

Oxana [17]

Using translations, it is found that the equation the represents the graphed function is:

$y = -f(x) - 3$ , given by option C.

----------------------------------

The parent function is $f(x) = \sqrt{x}$ .
As x increases, it's value increases. In the graph, as x increases, it decreases, thus it was multiplied by -1, that is, $-f(x)$ .
The parent function is defined for $x \geq 0$ , and the same is valid for the function in the graph, thus we have $f(x)$ and not $f(-x)$ .
The initial value of the parent function is $y = 0$ , here it is $y = -3$ , thus it was shifted down 3 units, that is, $y = -f(x) - 3$ , and the correct option is C.

An item that was selling for $80 is reduced to $42. Find the percent decrease in

Westkost [7]

Answer:

47.5%

Step-by-step explanation:

You have to first subtract 80 and 42 to find the decrease first. This is 38. Now, you have to divide this by the original number which is 80. So 38 divided by 80 is 0.475.

Now multiply this by 100.

You can easily move the decimal point to the right.

So you would get 47.5%

Hope this helped!
