The graph of f(x) = 18x is reflected about the x-axis and shifted upward 8 units. What is the equation of the new function, g(x)
stellarik [79]
<h3>Answer:</h3>
  • g(x) = -18x +8
  • y-intercept: (0, 8)
  • domain: (-∞, ∞)
  • range: (-∞, ∞)
<h3>Explanation:</h3>

Reflecting a function across the x-axis changes every y-value to its opposite. That is, f(x) = 18x becomes g(x) = -18x.

Shifting a function upward 8 units adds 8 to every y-value. That is, g(x) becomes g(x)+8.

The combined effect of these two transformations on f(x) is to give you ...

... g(x) = -18x + 8

You recognize this as the equation of a line in slope-intercept form, with the y-intercept being +8. That is, g(0) = -18·0 +8 = 8. The y-intercept is ...

... (0, 8)

The domain and range of any linear equation is "all real numbers," that is, ...

... (-∞, ∞).

Which of the following is an equation of a line parallel to 2x-y=-1?
Simora [160]

Although you didn't provide a list of options to choose from, I hope my explanation will help you  work this out with ease. :)

This equation is in a form known as "standard form." ax+by=c Standard form is commonly used, however for comparing slopes, there is a more efficient equation to use.

Point-slope form (y=mx+b) allows lines' slopes (y) and y-intercepts (b) to be quickly compared and contrasted. Let's put the equation into this form.

2x-y=-1

-2x      -2x

-y = -1 - 2x

*-1      *-1

y= 1 + 2x

Switch pieces around

y= 2x + 1

The slope is 2, the y intercept is 1.

<h2><u>Any line that rises 2 units up for every one unit right and that crosses over the vertical axis at any point other than 1 is your answer.</u></h2>

Which equation matches the graph shown?
pogonyaev

Answer:

  • C. y = 4x - 3

Step-by-step explanation:

<u>The line has a positive slope and negative y-intercept.</u>

  • m = 4, b = - 3

This is only matched by a choice C
