The general equation given is x^2 - 4x + y^2 = -3. Transform this to an equation of a circle of the form x^2 + y^2 = r^2.
Use completing the square method:
x^2 - 4x + 4 + y^2 = -3 + 4
(x - 2)^2 + y^2 = 1
the center of the circle is (2,0) and r = 1
To check if it intersects the y axis, find the value of the x-intercept.

<span> f(x) = 3(1/2)x is not properly formed; if you meant exponentiation here, please write the function as
f(x) = </span><span> f(x) = 3(1/2)^x.
The range is the set of all possible values of y (that is, all possible values of f(x). Try out a few x values and see what you get:
f(-5) = 3(1/2)^5 (note that this is positive)
f(0) = 3(1/2)^0 = 3 (this is positive)
f(4) = 3(1/2)^4 = 3/16 (this is positive)
There is no x value for which f is negative, and none for which f is 0. Given this info, what do YOU think the range of </span><span> f(x) = 3(1/2)^x is?
Write it in the form (a,b).</span>
