f(x)= -2x+1 {-2,0,2,4,6}
If x=-2, then -2(-2)+1 = 5
If x=0, then -2(0)+1 = 1
If x=2, then -2(2)+1 = -3
If x=4, then -2(4)+1 = -7
If x=6, then -2(6)+1 = -11

Graph of increasing exponential function going through point (0, 2)
=======================================================
Explanation:
Assuming you meant to say f(x) = 2(1.5)^x, then we can see the equation is an exponential and it is increasing. It is increasing because the base b = 1.5 is larger than 1.
Plug in x = 0 to find y
y = 2(1.5)^x
y = 2(1.5)^0
y = 2(1)
y = 2
We have x = 0 and y = 2 pair up together meaning (0,2) is on the function curve. This is the y intercept.

Answer:
2√(5/π) ≈ 2.523
Step-by-step explanation:
The radius can be found using the area formula:
A = πr²
20 = πr² . . . . . fill in the given value
20/π = r² . . . . . divide by π
√(20/π) = r = 2√(5/π) . . . take the square root and simplify
You can use your calculator to find a numerical value for this:
r = 2√(5/π) ≈ 2.52313

<em>Comment on the form of the answer</em>
Radicals are often considered to be in simplest form when they do not contain fractions or square factors. Here, the "simpler" form would be ...
r = (2/π)√(5π)
involving the irrational number π in two calculations. My preference for evaluating the expression for r is to leave it as √(20/π) or 2√(5/π).
