What is the range of f(x)= -3^x+4

V125BC [204]

Answer:

A. The set of all real numbers less than 4

Step-by-step explanation:

The range of the parent function $y=3^x$ is $y\in (0,\infty)$

The graph of the function $y=-3^x$ is reflected across the x-axis graph of the parent function, so the range of the function $y=-3^x$ is $(-\infty,0)$

The graph of the function $y=-3^x+4$ is translated 4 units up graph of the function $y=-3^x$ , so the range of the function $y=-3^x+4$ is $(-\infty,4)$ or the set of all real numbers less than 4.

nignag [31]

After 5 years, value doubles.
Hence after 5 years, value is 250 x 2 = 500
After another 5 years, value doubles.
500 x 2 = 1000
Ans: $1000

Method 2, using function given.
v(10) = 250 x 2(10/5) = $1000
