Afunction is defined by f(x)=5(2-x) what us f(-1)

15

Step-by-step explanation:

To evaluate f(- 1) substitute x = - 1 into f(x), that is

f(- 1) = 5(2 - (- 1)) = 5(2 + 1) = 5 × 3 = 15

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.
