Respuesta :

The correct answer is g(x)=1.5^x-4

Answer:

[tex]g(x)=1.5^{x}-4[/tex]

Step-by-step explanation:

we have

[tex]f(x)=1.5^{x}[/tex]

the y-intercept of the function f(x) is for x equal zero

so

[tex]f(0)=1.5^{0}=1[/tex]

The y-intercept of f(x) is the point [tex](0,1)[/tex]

The function g(x) in the graph has the y-intercept equal to [tex]-3[/tex]

The y-intercept of g(x) is the point [tex](0,-3)[/tex]

therefore

the rule of the translation is

[tex](0,1)------->(0,-3) [/tex]

[tex](x,y)------->(x,y-4) [/tex]

that means

the translation is [tex]4[/tex] units down

the equation of g(x) is equal to

[tex]g(x)=1.5^{x}-4[/tex]
