Answer:
<em>Correct answer: C. f(x) = 2(3)x + 4</em>
<u><em>(please note we changed the expression of the function to exponential form which we believe is the correct form of the question)</em></u>
Step-by-step explanation:
<u>Horizontal Asymptote</u>
The graph of a function is said to have a horizontal asymptote at y=a if one or both the following limits exist
The horizontal asymptotes are horizontal lines to which the function tends when x increases or decreases without limits.
Let's analyze each one of the options provided:
A. f(x) = 2x -4
No horizontal asymptote
B. f(x) = -3x + 4
No horizontal asymptote
C. f(x) = 2\cdot 3^x + 4
This function has a horizontal asymptote at y=4
D. 3\cdot 2^x -4
This function has a horizontal asymptote at y=-4
Correct answer: C.
Answer:
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
Step-by-step explanation:
Let the scale be and the dimensions of the rectangle being 4 inches and 5 inches, respectively. The scale (
), measured in inches per feet, is equivalent to the following rational number:
We can convert each length by dividing it by scale factor. That is:
Length
Width
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
