Usually you will see something like g(x) or f(x)

domain means all the x's

so, think of g(4) meaning g(x=4) and g(4 in the domain).

look for 4 on the domain side

you know that f(x) = y

range means all the y's

so its basically saying, look on the domain side for 4 and see what comes out (or =) on the range side.

Can I get help solving this ?
Rom4ik [11]

Answer:

x = -1.4

Step-by-step explanation:

Subtract the right side and simplify.

5 - 6(2 - x) - (x - 14) = 0

5 - 12 + 6x - x + 14 = 0 . . . . parentheses eliminated

7 + 5x = 0 . . . . . . . . . . . . . . terms collected

1.4 + x = 0 . . . . . . . . . . . . . . divide by 5

x = -1.4 . . . . . . . . . . . . . . . . . add the opposite of the constant

_____

Check

5 -6(2 -(-1.4)) = (-1.4) -14

5 - 6(3.4) = -15.4

5 -20.4 = -15.4 . . . . . true. Answer checks OK.
