Evaluate inverse functions <br><br> Find the following values f^-1(f(3.14)) <br> F(f(-7))
Margaret [11]

Answer:

1. 3.14

Step-by-step explanation:

If we have

f {}^{ - 1} (f(x)

That just equals

x

For example, consider function

f(x) = 2 {}^{x}

The inverse of that function is

y = 2 {}^{x}

x = 2 {}^{y}

log_{2}(x)  =  log_{2}(2 {}^{y} )

log_{2}(x)  = y

So

f {}^{ - 1} (x) =  log_{2}(x)

If we compose the function, f(x) into f^-1(x).

We get

log_{2}(2 {}^{x})  = x

That proof of that.

1. Here x=f^-1(3.14)and f(3.14) cancel out so the answer is 3.14

2. We first find f(-7) which is -12,

We then find f(-12)= 5 so the answer here is 5.

*5. Gina's sister is 9 years older than Gina. Their combined ages add up to
Wittaler [7]

Answer:

B. 20 years

Step-by-step explanation:

By using the process of trial and error, if Gina is 20 years old, that would mean her sister is 29 years old. This is because 20+9 is equal to 29. 29+20 sums up to 49.

What is the next term in the pattern? 3, 6, 9, 12, _________ What is the next term in the pattern? 48, 24, 12, 6, ________ What
TEA [102]

Answer:

The next in the first pattern is 15.

The next in the second pattern would be 3.

The next in the third pattern would be 32.

Step-by-step explanation:

In the first pattern, you can notice that the terms keep going up by 3. As a result, the next one is 3 higher (12 + 3 = 15)

In the second pattern, the next number is always half of the number before it. (6 * 1/2 = 3)

The last pattern shows each number being 10 less than the one before it. (42 - 10 = 32)
