2.<br> Which of the functions below is an inverse of the quadratic function f(x) = x2 - 3 ?

mezya [45]

Answer:

the inverse of the quadratic function $f(x) = x^2 - 3$ is $\mathbf{f^{-1}(x)=\pm \sqrt{x+3}}$

Step-by-step explanation:

We need to find inverse of the quadratic function $f(x) = x^2 - 3$

Let

$y=x^2-3$

Replace x and y

$x=y^2-3$

Now, we will solve for y

Adding 3 on both sides

$x+3=y^2-3+3$

$x+3=y^2$

Taking square root on both sides

$\sqrt{y^2}=\sqrt{x+3}\\y=\pm \sqrt{x+3}$

Now replace y with $f^{-1}(x)$

$f^{-1}(x)=\pm \sqrt{x+3}$

So, the inverse of the quadratic function $f(x) = x^2 - 3$ is $\mathbf{f^{-1}(x)=\pm \sqrt{x+3}}$

What is the total weight,in pounds , of 100 sharks that each weighs 5.015x10^3 in pounds ?

Grace [21]

Answer:

$5.015\cdot 10^4 pounds$

Step-by-step explanation:

The weight of an object is the magnitude of the force of gravity acting on the object. It is equal to the product between mass of the object (m) and acceleration of gravity (g):

$W=mg$

In this problem, we have 100 sharks; the weight of each shark is

$W=5.015\cdot 10^3 pounds$

When we have n objects, the total weight of the n object is n times the weight of each object:

$W_T = nW$

Therefore, since in this case

n = 100

The total weight of the 100 sharks is:

$W_T=(10)(5.015\cdot 10^3)=5.015\cdot 10^4 pounds$
