Study Notes

Graphs and Corresponding Equations

y = x^3: Represents a cubic function characterized by an S-shaped curve. It passes through the origin and has inflection points where the curve changes concavity.
y = 1/x^2: Depicts a rational function, specifically a hyperbola. It approaches the x-axis asymptotically, never touching it, and is always positive for x ≠ 0.
y = 1/x: Another rational function representing a hyperbola. It has vertical and horizontal asymptotes at x = 0 and y = 0 respectively, and it approaches these lines but never intersects them.
y = x: Linear function illustrated by a straight line with a slope of 1. It bisects the first and third quadrants, indicating a direct proportional relationship between x and y.
y = |x|: Absolute value function visualized as a V-shaped graph. It is symmetric around the y-axis, with a vertex at (0,0) and slopes of 1 and -1 in the first and second quadrants respectively.
y = x^2: Quadratic function with a U-shaped parabolic curve. It opens upwards, has its vertex at the origin, and is symmetric about the y-axis.
y = sqrt(x): Represents a square root function characterized by a gradual increase. Defined only for x ≥ 0, it starts at the origin and rises to the right, never touching the negative side of the axes.
y = 3sqrt(x): A scaled version of the square root function, amplifying the rise of the graph. Like y = sqrt(x), it only exists for x ≥ 0 and has a steeper slope due to the multiplier of 3.
