Which is a stretch of an exponential growth function? f(x) = Two-thirds (two-thirds) Superscript x f(x) = Three-halves (two-thirds) Superscript x f(x) = Three-halves (three-halves) Superscript x f(x) = Two-thirds (three-halves) Superscript x

Respuesta :

Answer:

f(x) = Three-halves (three-halves) Superscript x

f(x) = Two-thirds (three-halves) Superscript x

Step-by-step explanation:

Since, a function in the form of [tex]f(x) = ab^x[/tex]

Where, a and b are any constant,

is called exponential function,

There are two types of exponential function,

  • Growth function : If b > 1,
  • Decay function : if 0 < b < 1,

Since, In

[tex]f(x) =\frac{2}{3}(\frac{2}{3})^x[/tex]

[tex]\frac{2}{3} < 1[/tex]

Thus, it is a decay function.

in [tex]f(x) =\frac{3}{2}(\frac{2}{3})^x[/tex]

[tex]\frac{2}{3} < 1[/tex]

Thus, it is a decay function.

in [tex]f(x) =\frac{3}{2}(\frac{3}{2})^x[/tex]

[tex]\frac{3}{2} > 1[/tex]

Thus, it is a growth function.

in [tex]f(x) =\frac{2}{3}(\frac{3}{2})^x[/tex]

[tex]\frac{3}{2} > 1[/tex]

Thus, it is a growth function.
