b.

To determine

Predict the value of y for $x=2$, from the equation $\sqrt{\widehat{y}}=1.2+0.8x$.

c.

To determine

Predict the value of y for $x=2$, from the equation $\frac{1}{\widehat{y}}=1.2+0.8x$.

d.

To determine

Predict the value of y for $x=2$, from the equation $\widehat{y}=1.2+0.8\ln x$.

e.

To determine

Predict the value of y for $x=2$, from the equation $\log \widehat{y}=1.2+0.8\log x$.
