which of the following represents exponential growth?

[tex]y = 2x + 5[/tex]
[tex]y - x = 4[/tex]
[tex]x = 3[/tex]
[tex]y = 5 \times 2^{x} [/tex]

Respuesta :

Answer:

y = 5 × [tex]2^{x}[/tex]

Step-by-step explanation:

Exponential growth equations are usually in the form y = a × [tex]b^{x}[/tex].

So, y = 5 × [tex]2^{x}[/tex] is the best fit for that format.

The exponential growth:

[tex]y=a\cdot b^x[/tex]

Therfore your answer is [tex]y=5\times2^x[/tex]

--------------------------------------------------------

y = 2x + 5    it's a linear function in slope-intercept form

y - x = 4 → -x + y = 4   it's a linear function in standard form

x = 3   it's a vertical line
