Question

The table shows the height of a plant over time. Which type of function best models the data? Write an equation to model the data.

Year - Height
0 85
1 103
2 121
3 139
4 157

A. Quadratic: y=18x^2+85
B. Quadratic: y=85x^2+18
C. Linear: y=18x+85
D. Exponential: y=85×18^x

Answer 1

Linear y=18x+85
U can chk rate of change in y over rate of change of x is sconstant always =18
Which is called slope
Then use point slope formula u will get the same equation
