If f(x) = x + 4 and g(x)=x^2-1, what is m(g o f)(x)?
Andreas93 [3]

Until now, given a function  f(x), you would plug a number or another variable in for x. You could even get fancy and plug in an entire expression for x. For example, given  f(x) = 2x + 3, you could find f(y2 – 1) by plugging y2 – 1 in for x to get f(y2 – 1) = 2(y2 – 1) + 3 = 2y2 – 2 + 3 = 2y2 + 1.

In function composition, you're plugging entire functions in for the x. In other words, you're always getting "fancy". But let's start simple. Instead of dealing with functions as formulas, let's deal with functions as sets of (x, y) points:

Let f = {(–2, 3), (–1, 1), (0, 0), (1, –1), (2, –3)} and  

let g = {(–3, 1), (–1, –2), (0, 2), (2, 2), (3, 1)}.  

 

Find (i) f (1), (ii) g(–1), and (iii) (g o f )(1).

(i) This type of  exercise is meant to emphasize that the (x, y) points are really (x, f (x)) points. To find  f (1), I need to find the (x, y) point in the set of (x, f (x)) points that has a first coordinate of x = 1. Then f (1) is the y-value of that point. In this case, the point with x = 1 is (1, –1), so:

Consider the equation 4x + 1 = 2x + 5
Darya [45]

(a) Without solving the equation we can't determine whether its true or false.

(b) If x = 3

4x + 1 = 2x + 5

4(3) + 1 = 2(3) + 5

12 + 1 = 15 + 5

13 = 20

No, if x = 3, the equation will not be true.

(c) 4x + 1 = 2x + 5

4x - 2x = 5 - 1

2x = 4

x = 4/2

x = 2

This shows that x = 2 makes the equation true.

The variable y is calculated by multiplying the variable of x by 2. There is a third variable (variable z), and it is known that
juin [17]

Answer:

The correlation between two variables, let's say A and B, is given by:

r(A.B) = \frac{ \sum{A*B}}{ \sqrt{\sum{A^2}* \sum{B^2}}}

In our case, we know that:

y = 2*x

And:

r(X, Z) = 0.45

Then:

Now we want to find:

r(Y, Z)

Let's start with r(X, Z)

We know that:

X = Y/2

Then we can replace that in the correlation equation:

r(X.Z) = \frac{ \sum{X*Z}}{ \sqrt{\sum{X^2}* \sum{Z^2}}} = 0.45 \\

r(Y/2.Z) = \frac{ \sum{(Y/2)*Z}}{ \sqrt{\sum{(Y/2)^2}* \sum{Z^2}}} = 0.45 \\

r(Y/2, Z) =  \frac{ (1/2)*\sum{Y*Z}}{\sqrt{ (1/4)\sum{(Y)^2}* \sum{Z^2}}} =  \frac{ \sum{(Y)*Z}}{ \sqrt{\sum{(Y)^2}* \sum{Z^2}}} = 0.45

And in the third part, we have r(Y,Z), then:

r(Y, Z) = \frac{\sum{Y*Z}}{\sqrt{\sum{Y^2}*\sum{Z^2}}} = 0.45

The correlation of z with y is 0.45
