Answer:

The expression for Annika is $ 4x and Chris is $ (x + 10).

Step-by-step explanation:

Given that Annika has 4 times more than Bob and Chris has $10 more than Bob. So the expressions will be :

Annika = 4 × x = 4x

Chris = 10 + x

Find the inverse of the function and then determine whether the inverse is a function.

klemol [59]

as you already know, we start off by doing a quick switcheroo on the variables, and then we solve for y to get the inverse,

$\bf y=x^2+4\implies \stackrel{switcheroo}{x = y^2+4}\implies x-4=y^2\implies \pm\sqrt{x-4}=\stackrel{f^{-1}(x)}{y}$

and if you run a vertical line test on that expression, you'll find that it doesn't pass it, meaning is not a function.

Find all zeros of ƒ(x) = 2x^4 – 72x^2. Then determine the multiplicity at each zero. State whether the graph will touch or cross

AleksandrR [38]

Answer: See below

Step-by-step explanation:

To find the factor,

f(x) = 0

$\begin{aligned}&2 x^{4}-72 x^{2}=0 \\&2 x^{2}\left(x^{2}-36\right)=0 \\&x^{2}\left(x^{2}-36\right)=0 \\&x \times x \times(x-6) \times(x+6)=0 \\&\mathrm{x}=0,0,6,-6\end{aligned}$

So,

x = 0 multiplicity 2

x = -6 multiplicity 1

x = 6 multiplicity 1

For an even multiplicty, the graph touches the x-axis, and for an odd multiplicty, the graph crosses the x-axis

Therefore,

x = 0 multiplicty 2, Touch

x = -6 multiplicty 1, Cross

x = 6 multiplicty 1, Cross
