$y=ma^x\\\\(0;\ 10)\to m\cdot a^0=10\to m=10\\\\y=10a^x\\\\(1;\ 20)\to 10a^1=20\ \ \ |:10\\a=2\\\\\boxed{y=20\cdot2^x}\\\\check:\\(-2;\ 2.5)\to2.5=10\cdot2^{-2}\\\\2.5=10\cdot\dfrac{1}{2^2}\\\\2.5=10\cdot\dfrac{1}{4}\\\\2.2=2.2\ correct\ :)\\\\(2;\ 40)\to40=10\cdot2^2\\\\40=10\cdot4\\\\40=40$

$\boxed{y=10\cdot2^x}$

Mathematics

In summary, congruent shapes are figures with the same size and shape. the lengths of sides and the measures of the angles are identical. they’re exact copies, even if one is oriented differently. similar shapes are figures with the same shape but not always the same size
