The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)
<h3>What are exponential functions?</h3>
When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.
here usual form is specified below. They are written in several such equivalent forms.
The equation of the function is given as:
Set x = 0, 1, 2 and 3
This means that the graph of the function f(x) = 3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20).

W= width L= length = 2W
Area of Rectangle= Length * Widthsubstitute the area and the value of L in the formula
28,800 m^2= 2W * W
28,800= 2W^2divide both sides by 2 in an effort to isolate the variable w
14,400= W^2take the square root of both sides
√14,400= W^2
we want the negative and positive root of the radicand (the number under the radical symbol - 14,400 in this case)
120= w OR -120= w
LENGTHL= 2W= 2(120)= 240 meters
ANSWER: The side lengths are W= 120 m; L= 240 m. Even though W= -120 too, it is not a valid solution in this case since a field cannot have a negative value.
Hope this helps! :)
The slope is -3 and the intercept is (0,9) or just 9 in this case, I hope that it’s right
Answer:
1 1/4= 1.25
1.25 + 2.75= 4
On the number line, 4 will be plotted
