For all values of x, f(x) = x^2 + 3x and g(x) = x - 4 Show that fg(x) = x^2 - 5x + 4

Westkost [7]

Answer:

f(g(x)) = x² - 5x +4

Step-by-step explanation:

Explanation

Given that the functions

f(x) = x² + 3 x and g(x) = x-4

f(g(x)) = f(x -4) (∵ g(x) = x-4)

= (x-4)² + 3(x-4)

= x² - 2(4)x + 4² + 3x -12

= x² - 8 x + 16 + 3x -12

= x² - 5x +4

∴ f(g(x)) = x² - 5x +4

The following data points represent the number of children in each household on Maple Street. \qquad 0, 1, 2, 1, 20,1,2,1,20, co

zaharov [31]

Answer:

The mean number of the children is 1.2

Step-by-step explanation:

Given

Children: 0, 1, 2, 1, 2

Required

Determine the Mean number

The mean of a set is calculated as follows;

$Mean = \frac{\sum x}{n}$

Where x is the given set and n is the number of sets

In this case, n = 5 children

Hence;

$Mean = \frac{0 + 1 + 2 + 1 + 2}{5}$

$Mean = \frac{6}{5}$

$Mean = 1.2$

Hence, the mean number of the children is 1.2

Hey there!

To figure out what "x" means, you can divide the numbers 126 and 14 . . .

126 divided by 14 = 9

9 x 14 = 126

9 = x

----------------
x = 9
----------------

Hope this helps you.
Have a great day!
