Find the inverse of the function y = x2 - 12.

Semmy [17]

Good evening ,

Answer:

The inverse of the function y = x² - 12 is

x = √(y + 12)

Step-by-step explanation:

for y ≥ -12 :

x² - 12 = y ⇔ x² = y + 12 ⇔ x = √(y + 12).

What function represents the pattern shown in the table?

Pavlova-9 [17]

Given:

The table of values of an exponential function.

To find:

The function for the given table of values.

Solution:

The general exponential function is:

$y=ab^x$ ...(i)

Where, a is the initial value and b is growth factor.

From the given table it is clear that the function passes through the points (1,9) and (2,36). It means the function must be true for these two points.

$9=ab^1$ ...(ii)

$36=ab^2$ ...(iii)

On dividing (iii) by (ii), we get

$\dfrac{36}{9}=\dfrac{ab^2}{ab}$

$4=b$

Putting $b=4$ in (ii), we get

$9=a(4)^1$

$\dfrac{9}{4}=a$

Putting $a=\dfrac{9}{4},b=4$ in (i), we get

$y=\dfrac{9}{4}(4)^x$

$y=9(4)^{x-1}$

The function notation with variable n is:

$f(n)=9(4)^{n-1}$

Therefore, the correct option is D.

I really need help on these two. Its fine if you dont get both of them. i will give you 25 points

masya89 [10]

Answer:

He read 1/3 of the book on the second day

He didn't finish the book in two days.

Step-by-step explanation:

Lets find 3/5 of 5/9

If we said, find 3/5 of x, the answer would be 3/5x.

3/5*x = 3/5x

In the same way, $\frac{3}{5} *\frac{5}{9} = \frac{15}{45} = \frac{1}{3}$

He read 1/3 of the book on the second day

Does 5/9 + 1/3 equal to 1?

1/3 = 3/9

5/9 + 3/9 = 8/9

He didn't finish the book in two days.

Hope this helps :)

Have a nice day!
