Question

fin the amplitude, period, and phase shift of f(x)=-5sin(5x-2)
a. amplitude-5; period 2pi/5; phase pellet -2/5
b. amplitude 5; period 2pi/5; phase shift 2/5
c. aplitude -5; period 2pi; phase shift -2/5
d. amplitude 10; period 1pi/5; phase shift 2/5

Answer 1

B :)

Answer 2

b

Answer 3

how?

Answer 4

f(x)=af(kx-c)+h
f is the trig function... which in this case is sin...
to find the amplitude, it is the absolute value of a
to find the period, it is 2pi/k
to find phase shift it is c/k
to find vertical shift, it is h

Answer 5

the amplitude is the absolute value of -5, which is 5
the period is 2pi/k, which is 2pi/5
phase shift is c/k, which is 2/5
