What function g describes the graph of f after the given transformations?
Alex17521 [72]

After performing the transformation on f(x) = |x|+7; reflected across the x-axis and translated 4 units up. We get the function g(x) = -(|x| + 7) + 4

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = |x| + 7

First we reflect the function f(x) across the x-axis

Multiply the function by -1

F(x) = -(|x| + 7)

To translated 4 units up add 4 to the function.

g(x) = -(|x| + 7) + 4

Thus, after performing the transformation on f(x) = |x|+7; reflected across the x-axis and translated 4 units up. We get the function g(x) = -(|x| + 7) + 4

Help!!!
Artyom0805 [142]

Answer:

  C:  y+7=2/5(x+4)

Step-by-step explanation:

The point-slope form of the equation of a line with slope m through point (h, k) is ...

  y -k = m(x -h)

You are given m=2/5 and (h, k) = (-4, -7). Put these numbers into the form and simplify the signs:

  y -(-7) = 2/5(x -(-4)) . . . . . numbers put into the form

  y +7 = 2/5(x +4) . . . . . . . signs simplified . . . . matches choice C
