If you shift the linear parent function, (X) = x down 6 units, what is the
jeka94

Answer:

<h2>C. g(x) = x - 6</h2>

Step-by-step explanation:

For a parent function y = f(x) and n > 0:

f(x) + n : move the graph n units up

f(x) - n : move the graph n units down

f(x + n) : move the graph n units to the left

f(x - n) : move the graph n units to the right

===================================================

We have

f(x) = x

Transformation: 6 units down

f(x) - 6 = x - 6

Answer:

f(x) = -4x - 2

Step-by-step explanation:

To derive the function rule in slope-intercept form, f(x) = mx + b, we need to find the slope, m, and the y-intercept, b, of the graph given.

Using two points on the line, (-1, 2) and (0, -2), find slope (m) as shown below:

m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 2}{0 -(-1)} = \frac{-4}{1} = -4

m = -4

The line intercepts the y-axis at y = -2, therefore the y-intercept, b, = -2.

Substitute m = -4, and b = -2 into f(x) = mx + b.

The function rule in slope-intercept form would be:

f(x) = -4x +(-2)

f(x) = -4x - 2

A scale drawing of a park is 30 inches long and 24 inches wide. On the drawing, 1 inch is equal to 250 feet What are the actual
chubhunter [2.5K]

1 inch equals 250 feet.

Multiply the inches on the map by 250 to get total feet.


30 x 250 = 7,500 feet

24 x 250 = 6,000 feet


The park is 7,500 feet long by 6,000 feet wide
