Use f(x) = 1)2 and f^-1(x) = 2x to solve the problems. a) f(2) b)f^-1(1) c)f^-1(f(2))

Luden [163]

a) f (2) = 1

b) $f^{-1}(1)=2$

c) $f^{-1}(f(2))=2$

Step-by-step explanation:

$f^{-1}$ - Indicates that we have to find the inverse of the function

Given data:

$f(x)=\left(\frac{1}{2}\right) x$ --------> eq.1

$f^{-1}(x)=2 x$ ---------> eq.2

To find $f(2), f^{-1}(1), f^{-1}(f(2))$

Case a)

Now, substitute x = 2 in the equation 1 to find f (2)

$f(2)=\left(\frac{1}{2}\right) \times 2=1$

Case b)

Now, substitute x = 1 in the equation 2 to find $f^{-1}(1)$

$f^{-1}(1)=2(1)=2$

Case c)

In general,

$f^{-1}(f(x))=f\left(f^{-1}(x)\right)=x$

Thereby,

$f^{-1}(f(2))=2 \text { where } x=2$

Whats the equation to this

dybincka [34]

Answer:

y=1/2x + 3

Step-by-step explanation:

Slope is ∆y/∆x. In this case,

m = (6-3) / (6-0) = 3/6 = 1/2

Y-intercept is what the y-value is when the line intersects the y-axis. Because of the point (0,3), you know it's 3.

Select ALL the statistical questions that could be asked about a college?

sertanlavr [38]

Answer:

How many students attend the college each year?
What is the professor-to-student ratio at the college each year?
What percentage of applicants each year are accepted to the college?

Step-by-step explanation:

Statistical questions are questions that can be answered by collecting data that vary. The questions, "in what college is the state located?", "in what year was the college founded?", and "how many buildings are owned by the college" can collect data, however, the data does not vary.

Harry can first substitute 30 for t

He can then multiply $\frac{1}{3}$ by 30 to get a product of 10
