Step-by-step explanation: Stretches and compression change the slope of a linear function.
If the line becomes steeper, the function has been stretched vertically or compressed horizontally.
If the line becomes flatter, the function has been stretched horizontally or compressed vertically.
Horizontal Stretch/Compression by a factor of b
f(x)→ f(1• f(x→f(1 bx) • b > 1 stretches away from the y-axis.
• 0 < |b| < 1 compresses toward the y-axis.
• y-intercepts remain the same.
Vertical Stretch/Compression by a factor of a
• f(x) → a f(x) • a > 1 stretches away from the x-axis.
• 0 < |a| < 1 compresses toward the x-axis.
• x-intercepts remain the same.Stretches and compression's change the slope of a linear function.
