We need an equation for this, theres no 'formula' for doing this (ignoring the quadratic formula, as that is a long-winded way of factorising a quadratic equation)
Domain:
{-1, 3, 6}
Range:
{4, 5, 6}
This is a well known joke:
Why six afraid of seven? Because seven ate nine!
It is supposed to be a "word game" where instead of writing eight, the authour wrote ate, which sound the same but means something different.
Hope it helped,
Happy homework/ study/ exam!
To solve for a number x,
3x+4x-2=15
7x-2=15
7x=17
x=2 3/7
or x=~2.43
was one of your answer choices either of the first two equations?
