Given:
The graph of an exponential function.
To find:
The function in the form of
.
Solution:
The general form of an exponential function is
...(i)
From the given graph it is clear that the function passes through the points (0,4) and (1,7). It means these points will satisfy the function.
For x=0 and f(x)=4,



For x=1 and f(x)=7,

Putting a=4, we get


Substitute a=4 and
in (i).

Therefore, the required exponential function is
.
Answer:
The average installation cost of laminate flooring ranges between $2 and $8 per square foot.
Step-by-step explanation:
The sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.
<h3>Area of a sector</h3>
The coloured portion of the circle is known as a sector. The formula for calculating the area of a sector is given as:
Area of a sector = θ/360 * πr²
where
θ is the central angle
πr² represents the area of a circle.
Therefore the best statement that explains the formula is expressed as the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.
