Find the exponential function f(0) = Ca* whose graph goes through the points (0, 2) and (3, 16).

a=
C=

Sagot :

Step-by-step explanation:

[tex]2 = c(a) {}^{x} [/tex]

[tex]2 = c(a) {}^{0} [/tex]

[tex]2 = c(1)[/tex]

[tex]2 = c[/tex]

So our function is

[tex]y = 2(a) {}^{x} [/tex]

[tex]16 = 2(a) {}^{x} [/tex]

[tex]8 = a {}^{3} [/tex]

[tex]a = 2[/tex]

So our function is

[tex]y = 2(2) {}^{x} [/tex]
