First, you should rearrange your equation using simple algebra

2x-3y-18=0
2x-18=3y
(2x/3)-6=y

the y intercept has an x coordinate of 0, so substitute 0 as x in your equation to find the y-int.

the x intercept has a y coordinate of 0, so substitute 0 as y in your equation and algebraically solve for the x-int

to make the table of values, just substitute different values in for x in the equation

F(x) = 4x + 7, g(x) = 3x2<br><br> Find (fg)(x).
Brums [2.3K]
F(x) = 4x + 7
g(x) = 3x²

(f · g)(x) = 3x²(4x + 7)
(f · g)(x) = 3x²(4x) + 3x²(7)
(f · g)(x) = 12x³ + 21x²
