For the function, f(x) =1/4 x - 2, find x if f(x) = -1. a. x=-9/4 b=x=4 b=x=1/4 x=-7/4

For this case we have a function of the form , where

We want to find the value of "x" when the function has the value of -1, that is, when

So:

We clear "x":

We add "2" to both sides of the equation:

We multiply by "4" on both sides of the equation:

So, whenthen

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.
