Answer:
y = 1.00+0.10 x (if this is what you meant)
Step-by-step explanation:
Given that a taxi has a minimum charge of 1 dollar upto 1/10 mile and adds 0.10 for every additional 1/10 mile.
If a person travels <=1/10 miles his charges are 1 dollar
If he travels >1/10 miles charges are 1 dollar +0.10(extra miles 1/10)
Let y be the charges and x be the no of 1/10 miles.
Then the equation for y in terms of x would be
y =1.00 +1/10(x)
y = 1.00+0.10 x
rolling a 5 is a 1/6 probability
tossing tails is a 1/2 probability
doing both is a 1/6 * 1/2 = 1/12 probability
The slope is rise/run so 2/2
An inverse function simply produces points (y,x) for each point (x,y) of the parent function. So to find an inverse function you must solve for the independent variable and then simply sway the variable labels...
y=4x+8 so we want to solve for x, subtract 8 from both sides
y-8=4x, divide both sides by 4
(y-8)/4=x, now simply swap variable labels...
y=(x-8)/4
f^-1(x)=(x-8)/4
