Svetlanka [38]

You have two choices: the easiest is to turn every fraction to its numerical equivalent:

-\dfrac{9}{10}=-0.9,\ \ -\dfrac{3}{7}\approx -0.42857,\ \ -\dfrac{3}{4}=-0.75,\ \ -\dfrac{6}{5} = -1.2, -\dfrac{4}{3}\approx -1.33

Now, remember that negative numbers are ordered in the opposite way with respect to positive numbers (for example, 4 is larger than 2, but -4 is smaller than -2). So, the order is

-\dfrac{4}{3} < -\dfrac{6}{5} < -\dfrac{9}{10} < -\dfrac{3}{4} < -\dfrac{3}{7}

Alternatively, you can convert all the fractions so that they have the same denominator. In this case, you will need the least common multiple of 10, 7, 4, 5 and 3, which is 420. Once you do so, you can easily order the fractions using numerators only.

Use the graph to evaluate the function for the given input value.
Angelina_Jolie [31]

The  evaluation of the function for the given f(-1), f(1)   input value is  mathematically given as

  • f(-1) = -8
  • f(1) = -12

<h3>What is the evaluation of the function for the given f(-1), f(1)   input value?</h3>

In the field of mathematics, an assignment of one element from set Y to each and every element in set X is the definition of a function. This particular set, X, is referred to as the function's domain, and this particular set, Y, is referred to as the function's codomain. Historically, functions have been seen as an idealization of the way in which one variable relies on another variable.

-1 and 1 are both considered to be input when evaluating the function f, which is represented by the graph.

Since the inputs are on the x-axis, the graph demonstrates that the value of the function f at -1 is about -8 when x equals -1.

When x equals 1, the value of the function f is close to -12.

If you divide 25 by 12, then you will get 2.083 (3 repeating). If we round that, it will turn to about 3 inches.
