Suppose that the function f is defined, for all real numbers, as follows.
Veseljchak [2.6K]

The solutions of the function are:

  • When f(x) = -4, the solution is -4
  • When f(x) = -2, the solution is -5/2
  • When f(x) = 0, the solution is -1

<h3>How to solve for the equation </h3>

The equation is given as

\frac{3}{4} x-1\\\\

When x = -4

3/4 * -4 -1

= -12/4 - 1

= -4

When x = -2

3/4*(-4) - 1

= -6/4 - 1/1

Take the lcm

-10/4

= -5/2

When x = 0

3/4(0) - 1

= -1

When f(x) = -4, the solution is -4

When f(x) = -2, the solution is -5/2

When f(x) = 0, the solution is -1

Correctly order the following numbers from LEAST to GREATEST:
ivanzaharov [21]

- 7 1/5 <  - 2.3 < 0 < π  < 23/7 is ascending order of these numbers.

What do descending order and ascending order mean?

  • Climbing down the stairs of numbers starting with their highest value is another way to think of descending.
  • The slide is descended while moving down it.
  • Ascending order, in which the numbers are organized from lower value to higher value, is the reverse of falling order.

The values are 0 , -2.3 , π , 23/7 , -71/5

first simplify all the values  0 , - 2.3 , 3.14 , 3.28 , -7.2

now arrange all value in Ascending order

 - 7.2 < -2.3 < 0 < 3.14 < 3.28

- 7 1/5 <  - 2.3 < 0 < π  < 23/7
