TRUE
|
|
|
I4x+3I+12=4 has a solution?

YOU CANNOT HAVE AN ABSOLUTE VALUE EQUAL TO A NEGATIVE NUMBER |
|
|
the slope of a vertical line is 0?
|
false
THE SLOPE OF THE HORIZONTAL LINE IS 0 |
|
|
A FUNCTION IS ALWAYS A RELATION?

|
|
|
( f (composition) g ) (x) means
|
f [g(x) ]
f of g of x don't confuse for multiplication |
|
|
IxI=-6
does this have a solution ? |
no because an absolute value can't have a negative number.
|
|
|
what do you think of for the formula for slope?
|
1. changing y over changing of x
2. the rise over run |
|

(neg infinity to positive infinity)
|
|
|
the domain of vertical line?
|
the domain would be the number that the x is equal to.
