Do u still have this homework or is it old
Answer:
Step-by-step explanation:
one head is 1/2 tails twice is 1/4
multiply and get 1/8 but thats not the answer yet
a possibility could be htt or tht
so u muiltiply by number of possibilities of one head which 3!/2!
<u>3/8</u>
Common difference r will be the difference between next two values of number row, so we take e.g. second minus first: r=9.4-6=3.4. You can see, that this value is constant as we go through next pairs of values.
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solve for "y".
![\bf \stackrel{f(x)}{y}=x^2-10\implies \stackrel{switcheroo}{x=y^2-10}\implies x+10=y^2\implies \sqrt{x+10}=\stackrel{f^{-1}(x)}{y}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7Bf%28x%29%7D%7By%7D%3Dx%5E2-10%5Cimplies%20%5Cstackrel%7Bswitcheroo%7D%7Bx%3Dy%5E2-10%7D%5Cimplies%20x%2B10%3Dy%5E2%5Cimplies%20%5Csqrt%7Bx%2B10%7D%3D%5Cstackrel%7Bf%5E%7B-1%7D%28x%29%7D%7By%7D)
