We can substitute y in the second equation with the first equation since y = y. The solution of the linear system is (1, 6). You can use the substitution method even if both equations of the linear system are in standard form. Just begin by solving one of the equations for one of its variables.

Answer:

$y=0.2*4^{x}$

Step-by-step explanation:

Notice when x increases 1, y is 4 times the previous one, so

the function is like $y=C*4^{x}$

To determine the constant C, put any pair of (x, y)

Use x = 0, y = 0.2, so

0.2 = $C*4^{0}$ = C * 1 = C

then $y=0.2*4^{x}$
