The graph of y = x 2 has been translated 7 units to the left. The equation of the resulting parabola is . y = (x - 7) 2
y = (x + 7) 2
y = x 2 - 7
y = x 2 + 7

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
