Describe a series of transformations that takes A to B then B to C. (A) Reflection across the x-axis… then… rotation 90 degrees clockwise

(B) reflection across the y-axis… then… rotation 90 degrees clockwise

(C) reflection across the x-axis… then… rotation 90 degrees counterclockwise

(D) reflection across the y-axis… then… rotation 90 degrees counterclockwise

its a straight line parallel to the time axis

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

asnwer is (g o h o f)(x) = 2x - 6/x + 7

step-by-step explanation:

given,

f(x) = x - 3/x

g(x) = x + 3

h(x) = 2x + 1

we need to find : (g o h o f)(x)

we can write (g o h o f)(x) = g[ h{ f(x) } ]

so first we find h{f(x)}

h{f(x)} = f(x) + 3 = (x - 3/x) + 3

h{f(x)} = x - 3/x + 3

now we find g[ h{ f(x) } ].

g[ h{ f(x) } ] = g(x - 3/x + 3)       {plug h{f(x)} = x - 3/x + 3 in g[h{f(x)}] }

g(x - 3/x + 3) = 2 (x - 3/x + 3) + 1

                    = 2x - 6/x + 6 + 1

                    = 2x - 6/x + 7

hence we get (g o h o f)(x) = 2x - 6/x + 7
