$y=35\cdot (1.6)^x.$

Step-by-step explanation:

Find the exponential function in a form $y=a\cdot b^x.$

1. At x=0,

$35=a\cdot b^0=a.$

2. At x=1,

$56=35\cdot b^1\Rightarrow b=\dfrac{56}{35}=\dfrac{8}{5}=1.6.$

Therefore, the expression for the exponential function is

$y=35\cdot (1.6)^x.$

Note that

$y(-1)=35\cdot (1.6)^{-1}=\dfrac{35}{1.6}=21.875$

and

$y(2)=35\cdot (1.6)^2=35\cdot 2.56=89.6.$
