Match each combination to the corresponding value. Two real-valued functions, Ax) and gx), are defined as x) = x + 6x +9 and g(x) = x2 - 9. Find the results of combining these functions.
(f+g)(x)
(f-9)(x)
(fx g)(x)
(f=9)(x)
6(x+3)
2x(x + 3)
(+3)
(1-3)
X4 + 6x2 - 54x-81

it has to be a.

f(x) = y

f(-3) = -5

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
