the functions f(x) and g(x) are described below: f(x) = 7x + 9 g(x) = 7x − 4 the graph of g(x) is obtained by shifting down the graph of f(x) by units. numerical answers expected! answer for blank 1

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
