Step-by-step explanation:

find slope first

38-8/-14-(-20) = 5

y = 5x + b

find y intercept by sub in any set value show as long as they are belongs together

8 = 5(-20) + b

8 = -100 + b

108 = b

y = 5x + 108

Given a quadratic function in vertex form:

Alja [10]

Answer:

See below

Step-by-step explanation:

Part A

A vertical stretch takes place when $a\cdot f(x)$ given that $|a| > 1$

Part B

A vertical compression takes place when $a\cdot f(x)$ given that $0 < |a| < 1$

Part C

A vertical stretch is different than a horizontal compression:

In a vertical stretch, the input stays the same, but the output is multiplied by the scale factor
In a horizontal compression, the output stays the same, but the input is multiplied by the scale factor

Part D

A reflection across the x-axis means that the output, our y-variable, is the opposite sign. This means that all values of $a$ must be negative such that $a\cdot f(x)$ as mentioned in parts A and B. Also, in part C, since our scale factor is negative, the output is the only one being multiplied by the scale factor.

The function g(x) is the inverse of the function f (x) = (x + 1)2 + 2, when x < -1

kondaur [170]

9514 1404 393

Answer:

g(x) = -√(x -2) -1

Step-by-step explanation:

We note the domain of f(x) is x ≤ -1. The is the range of the function g(x).

The inverse function is the solution to ...

x = f(y)

x = (y +1)² +2

x -2 = (y +1)²

-√(x -2) = y +1 . . . . . . . we are interested only in the negative values

y = -√(x -2) -1

The inverse function is ...

g(x) = -√(x -2) -1
