Answer:

The correct option is c.

Step-by-step explanation:

In a quadratic function, for more that one inputs there exist same output.

The rate of change of a line and linear  function is constant.

Conditions of an exponential function:

1. The rate of change of a exponential function is not constant. The exponential function increase or decrease gradually.

2. Domain of an exponential function is all real numbers.

3. For one input there exist a unique output.

From the given graph it is clear that the function is increasing at increasing rate. The given graph satisfy all the conditions of an exponential function, so the given graph represents an exponential function.

An exponential function is defined as

f(x)=ab^x

The graph passing through the points (1,1) and (2,3).

1=ab^1                     ..... (1)

3=ab^2                     ..... (2)

On solving (1) and (2), we get

a=\frac{1}{3},b=3

f(x)=\frac{1}{3}(3)^x

Therefore the correct option is c.

nevsk [136]

Answer: 92.5 inches by 100 inches.


Step-by-step explanation:

1. You know that 1 inch represents 8 feet and the dimensions of the building are 740 feet by 800 feet, therefore, you must apply the proccedure shown below:

\frac{740ft*1in}{8ft}=92,5in

\frac{800ft*1in}{8ft}=100in

Answer:

50 Degrees

Step-by-step explanation:

Since they already have 40 degrees for you, and a little square means a right angle (90 Degrees), then 40 + 90 is 130. The interior angles of a triangle always add up to 180, so 180 - 130 is 50. The answer is therefore 50 degrees.
