Question

1) (0,0),(1,1),(2,8),(3,27)

2) (0,1),(1,2),(2,5),(3,10)

3) (0,0),(1,3),(2,6),(3,9)

4) (0,1),(1,3),(2,9),(3,27)

Answer 1

1) (0,0),(1,1),(2,8),(3,27)

Cubic function: y = x³

2) (0,1),(1,2),(2,5),(3,10)

Quadratic function y = x² + 1

3) (0,0),(1,3),(2,6),(3,9)

Linear function y = 3x

4) (0,1),(1,3),(2,9),(3,27)

Exponential function: y = 3^x
