What is the range of the function f(x) = |x| – 3?

Mathematics

Likurg_2 [28]3 years ago

Why not draw the graph of y=|x|?  It has a v-shape, and the vertex is at (0,0).

The graph of f(x) = |x| - 3 looks exactly the same, EXCEPT that the whole graph of |x| is shifted 3 units downward.  The smallest value that y can have is therefore -3.

Can you now figure out the range of f(x)?

The value of y varies directly with x. If x = 8, then y = 96. What is the value of x when y = 168?
patriot [66]

Answer:

  • x = 14

Step-by-step explanation:

<u>Direct variation equation:</u>

  • y = kx, where k is constant of variation

<u>Given:</u>

  • 96 = 8k
  • k = 96/8
  • k = 12

<u>The equation is:</u>

  • y = 12x

<u>Find the value of x when y = 168:</u>

  • 168 = 12x
  • x = 168/12
  • x = 14

Convert 0.83 into a fraction.​
Anastasy [175]

0.83 * 100 = 83, so 0.83 = 83/100.

But in case you meant the slightly more interesting repeating decimal, 0.8333...:

Let <em>x</em> denote this number. Then

10<em>x</em> = 8.333...

100<em>x</em> = 83.333...

==>  100<em>x</em> - 10<em>x</em> = 83.333... - 8.333...

==>  90<em>x</em> = 83 - 8 = 75

==>  <em>x</em> = 75/90 = 5/6
