I need help with part b please

The accompanying values are a set of data for y, the amount of money (in thousands of dollars) contributed to the
alumni association at a certain university from a certain graduate class, and x, the number of years following
graduation for that class. Complete parts (a) through (c) below.
Click the icon to view the contribution data.
(a) Fit a regression model of the type μyx = ẞo +ẞ1×1.
ŷ= -587 + (428) ×₁
(Round to the nearest integer as needed.)
(b) Fit a quadratic model of the type μyx = Po +ẞ₁×₁ +B₁₁x²₁.
ŷ = ] + (1) ×₁ + ( )×
(Round the x²-coefficient to one decimal place as needed. Round all other constants and coefficients to the nearest
integer as needed.)
