Answer:
where is the polynomial (?)
Step-by-step explanation:
Keywords:
<em>Medium sodas, buy, dollars, divide
</em>
For this case we must find the amount of medium sodas that Natalie's group can buy, taking into account that they have 20 dollars and that each medium soda costs 1.25 dollars. To solve, we must divide:
Let "x" be the number of medium sodas you can buy, then:

So, Natalie's group can buy 16 medium sodas with 20 dollars
Answer:
16 medium sodas
We have that
y = 2x²<span> + 2
step 1
</span><span>exchange the value of x for y and the value of y for x
</span>y = 2x² + 2------> x=2y²+2
step 2
clear y variable
x=2y²+2----> 2y²=x-2----> y²=[(x-2)/2]-----> y=(+/-)√[(x-2)/2]
step 3
the inverse is
f(x)-1=(+/-)√[(x-2)/2]
