Which of the following is true for the relation f(x) = x2 + 8? Only the inverse is a function. Both the equation and its inverse
Alchen [17]

<u>ANSWER</u>

Only the equation is a function

<u>EXPLANATION</u>

f(x)=x^2+8 is graphed above with its inverse f^{-1}(x)=\pm \sqrt{x-8}.


We perform the vertical line test for both the equation and its inverse.


The equation f(x)=x^2+8 passed the vertical line hence it is a function.

However, f^{-1}(x)=\pm \sqrt{x-8} failed the vertical line test, hence it is not a function.

A price is decreased from £800 to £640. Calculate the percentage change.
Anni [7]
<span>There is a decrease of 20% from ÂŁ800 to ÂŁ640.

    A change from 800 to 640 represents a negative change (decrease) of -20% Using the formula :

   Percent change = [(800 - 640) / 800] x 100 = -20 % (decrease)

       800 is the old value and 640 is the new value. In this case we have a negative change (decrease) of -20 percent because the new value is smaller than the old value.</span>
