Question

Let f(x)=-4x-2 and g(x)=5x-6. find F(little black circle ) g and state it's domain

Answer 1

they all are real numbers
but is 6 or 1

Answer 2

no domain is all real numbers.
\[f(g(x))=f(5x-6)=-4(5x-6)-2\]

Answer 3

now we can multiply and combine like terms
\[f(g(x))=-4(5x-6)-2=-20x+24-2=-20x+22\]

Answer 4

-20x

Answer 5

this is a line, so domain all real numbers.

Answer 6

20

Answer 7

\[-20x+20\]

Answer 8

34 or 12 are in the answer somewhere

Answer 9

or 14

Answer 10

no i don't see 34 or 14 anywhere in \[f(g(x))\]

Answer 11

possible answers
..-20x^2+14x+12 all real except
..8x^2+34x-30 all real except 1
...8x^2+34-30 all real
...-20x^2+14x+12 all real

Answer 12

OOOOOOhhhhhhhhhhhhhhhhh

Answer 13

\[fg(x) not f(g(x))\]

Answer 14

f o g

Answer 15

-20x^2+14x+12 all real except 6

Answer 16

well if that is it, i am right. if it is f times g then one of those is the answer. but that open circle does not mean mulitply

Answer 17

no it would not be all real except 6 because it is a polynomial so it would be all real numbers.

Answer 18

no it is a close circle

Answer 19

\[-20x^2+6x+8\]

Answer 20

nope you are right sorry

Answer 21

no you are right

Answer 22

\[-20x^2+12x+12\]

Answer 23

okay yeay

Answer 24

domain all real numbers
