Need explanation 20 points The function f is such that f(x) = 2x - 6 Find f^-1(x)

Dvinal [7]

HEYA! <3

Explanation :

GIVEN :

f(x) = 2x - 6

TO FIND :

Inverse of f(x) i.e $f ^{ - 1} (x)$

SOLUTION :

FOLLOW THESE THREE STEPS :

LET Y = f(x)

$\longrightarrow \tt{y = 2x - 6}$

$\longrightarrow{ \tt{ \: 2x - 6 = y}}$

MAKE X A SINGLE TERM IN LHS SIDE

$\longrightarrow{ \tt{2x = y + 6}}$

$\longrightarrow{ \tt{x = \frac{y + 6}{2} }}$

INTERCHANGE THE VALUE OF X AND Y

$\longrightarrow{ \tt{y = \frac{x + 6}{2} }}$

Hence ,

$\boxed{ \boxed{ {f}^{ - 1} (x) = \sf{ \bold{ \frac{x + 6}{2} }}}}$

Hope I helped!

Have a wonderful day / night !

In a certain liberal arts college with about 10,000 students, 53% are males. If two students from this college are selected at r

tamaranim1 [39]

Answer:

There is a 50.18% probability that they are of the same gender.

Step-by-step explanation:

We have these following percentages:

53% of the students are males.

47% of the students are females.

If two students from this college are selected at random, what is the probability that they are of the same gender?

The probability that each is male is 53%. So the probability of both being males is

$P_{MM} = 0.53*0.53 = 0.2809$

The probability that each is female is 47%. So the probability of both being females is

$P_{FF} = 0.47*0.47 = 0.2209$

The probabilty that both are the same gender is:

$P = P_{MM} + P_{FF} = 0.2809 + 0.2209 = 0.5018$

There is a 50.18% probability that they are of the same gender.
