If y(x) = 3x – 2 and g(x) = 2x+1, find (f- g)(x).

Mathematics

r-ruslan [8.4K]3 years ago

Answer:

(f- g)(x) = x - 3

Step-by-step explanation:

(f- g)(x) = f(x) - g(x)

This means that you have to subtract the two equation.

If f(x) = 3x - 2 and g(x) = 2x + 1

Then

f(x) - g(x) = [3x - 2] - [2x+1]

= 3x - 2- 2x - 1

= x - 3

∴ (f- g)(x) = x - 3

The interval where the function is increasing is (3, ∞)

<h3>Interval of a function</h3>

Given the rational function shown below

g(x) = ∛x-3

For the function to be a positive function, the value in the square root  must be positive such that;

x - 3 = 0

Add 3 to both sides

x = 0 + 3

x = 3

Hence the interval where the function is increasing is (3, ∞)

On one map of a town, the scale from the town to the map is 12mi:
Yuri [45]

The distance between the school and the library is less. Then the library is closer to school.

<h3>What is dilation?</h3>

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

There is no effect of dilation on the angle.

On one map of a town, the scale from the town to the map is 12mi:3cm.

The school is 2.5cm from the grocery store on this map.

Then the distance between the school and the grocery store will be

⇒ (12 / 3) x 2.5

⇒ 10 miles

On a different map of the same town, the scale from the town to the make is 12mi: 2cm.

The school is 1.5cm from the library on that map.

Then the distance between the school and the library will be

⇒ (12 / 2) x 1.5

⇒ 9 miles

Thus, the distance between the school and the library is less.

Then the library is closer to school.

More about the dilation link is given below.
