Question

Guys i am very much confused with quadratic inequalities, plz can any one explain it clearly.

Answer 1

Sure do you have an example to go through or will I make one up?

Answer 2

f(x) > 0 and f(x) > x^2 + x - 6, what make this two different.

Answer 3

i think u must find the value of x..then u can see the dfferent

Answer 4

what is f(X)?

Answer 5

hmmm...yes,what is f(x)...

Answer 6

just in case you are given a quadratic equation. and you are told to shade f(x)

Answer 7

Are you finding the values for x
x^2+x-6<0 ?

Answer 8

you should first solve the equation when you are dealing with inequalities

Answer 9

I know how to find x and how to shade but i am confused when to shade the region below or above the parabola and when to just shade the parabola.

Answer 10

(x-2)(x+3)<0
-3<x<2

Answer 11

just plug in some numbers and check whether the f(X) is positive

Answer 12

juz see the positive or negative number...so can u know the shaded region...

Answer 13

if the equation says f(x) < 0 that means that all numbers have their y coordinate less then 0, so shade everything below y = 0.

Answer 14

any comment on the photos? Everything clear?

Answer 15

Answer 16
