Question

does this increase or decrease if so by what : When f(x) becomes − • f(x)

Answer 1

@jim_thompson5910

Answer 2

how did you make the black dot?

Answer 3

and your question depends on f(x)

Answer 4

oh sorry its when f(x) becomes -1/2

Answer 5

-1/2 times f(x)

Answer 6

you guys there? sorry im jsut about to explode with this. so frustrating ):

Answer 7

Is that the whole question or are you just typing a part of it?
What is f(x) equal to?

Answer 8

ill send the whole question.

Answer 9

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing, and the end behavior when the following changes are made. Make sure to account for even and odd functions.


When f(x) becomes f(x) + 2
When f(x) becomes − • f(x)

Answer 10

i already did the first part. now just need help with the second

Answer 11

sorry phone call

Answer 12

@FibonacciChick666 can you help because andi says she is about to explode :)

Answer 13

so, you want to write a generic polynomial in slope intercept to begin

Answer 14

the Q doesnt say nothing about slope

Answer 15

If the original polynomial function f(x) had a positive y-intercept, then, the -1/2 * f(x) will have a negative y-intercept and its magnitude will be one-half of the original y-intercept.

Answer 16

well you sort of make up the coefficients, but what we want is something we can work with

Answer 17

thank you so much! that is what i needed! thanks (:

Answer 18

If the original polynomial function f(x) had a negative y-intercept, then, -1/2 * f(x) will have a positive y-intercept and its magnitude will be one-half of the original y-intercept.

Answer 19

wait so is it positive or negative?

Answer 20

I considered two cases: positive y-intercept and negative y-intercept.
But if you prefer a simpler answer then: the y-intercept of -1/2f(x) will be -1/2 * the y-intercept of f(x).

Answer 21

you also need to consider even and odd

Answer 22

this one would be odd so it would be negative?

Answer 23

it will go down?

Answer 24

Transforming f(x) to -1/2f(x) will REVERSE the intervals where the function is increasing / decreasing. In other words, intervals where f(x) was increasing will have -1/2 * f(x) decreasing and vice-versa.

Answer 25

The end behaviors will also be reversed.
The end behavior of -1/2 * f(x) will be the exact OPPOSITE of the end behavior of f(x).

Answer 26

All of the above answers for part b) will be the same whether f(x) is an odd or an even function.

Answer 27

thank you so much grat explainashin love you for this !

Answer 28

can you do me a little favor? (:
