(3,4) (4,-3) (7,4) (3, 8)
(6,-5) (7, -3) (8, -1) (9, 1)
(2, -2) (5, 9) (-5, -7) (1, 4)
If f(x) = 2x+1, what would the function look like once you substitute in a 1 to find f(1)?
f(x) = 21+1
f(1) = 2 (1) + 1
f(1) = 2x (1) + 1
If f(x) = -3x - 8, find f(-1).
f(-1) = 5
f(-1) = -5
f(-1) = -12
f(-1) = -10
If f(x) = x2-x+3, what would the function look like once you substitute in a -3 to find f(-3)?
f(-3) = -32-3+3
f(-3) = (-3)2 -(-3)+3
f(-3) = (-3)2 -3+3
