Which sequence of buttons correctly starts Quadratic Regression on a TI-84?

Y= → GRAPH → TRACE

STAT → EDIT → 1-Var Stats

STAT → CALC → 5: QuadReg

2nd → MODE → QuadGraph

1

Where do you enter your x-values when preparing data for QuadReg?

L1

L2

Y=

X,T,θ,n

1

Which command correctly stores the regression equation into Y1?

VARS → WINDOW → Y1

MATH → SOLVER → Y1

Y= → ENTER → ALPHA

VARS → Y-VARS → Function → Y1

1

Which of the following is the correct full process for QuadReg?

Y= → Graph → QuadReg

STAT → Edit → enter L1/L2 → STAT → CALC → QuadReg → Store RegEQ in Y1

STAT → CALC → LinReg → Y1

MODE → Func → QuadMode
