If (fx)=5x, what is f^-1(x)

Mathematics
1 answer:
zysi [14]4 years ago

Answer:

x/5

Step-by-step explanation:

To get the inverse function you need to leave the x alone and then switch variables ( f(x) = y)

f(x) = 5x

y = 5x

y/5 = x

Now that x is alone you switch the x for y and the y for x and you get:

x/5 = y

And this new y is the inverse function of f(x) ( f^-1(x))

f^-1(x) = x/5

Answer

I assume you're talking about 6-7, so on the left lines, you already did it, you just regularly subtract the numbers, and then on the right lines, you round the first problem to the nearest ten, remember five and up, round up, so for question 6 the new number model would be 90-40=50. since 93 rounds down to 90 and 38 rounds up to 40. continue to do that and write the entire model AND answer on the line to the right. hope this helps

Talja [164]
The domain of a function is the set of values that can be used for x.
Here, x represents the number of tacos.
He can order no taco, so x = 0.
He can order 1 taco, where x = 1.
He can order 2 tacos, so x = 2.
He cannot order a fraction of a taco, so x cannot be a mixed numeral.
He can order as many tacos as he wants, so x can be any whole number, 0 to infinity.
The domain is all whole numbers.
