How do we find x-intercepts using factored form? How do we find y-intercepts using factored form?
x-intercepts: Set each factor equal to 0.
y-intercepts: Convert to standard, look for the number without a variable (d-value)
What do each of the values do to the function (What do A, C, and D do to the function?
T(x)=A(x-C)^3+D
A: Negative - Reflection, Whole number - Vertical Stretch, Fraction - Vertical Compression
C: x-C - Right, x+C - left
D: +D - Up, -D - Down
