Step-by-step explanation:
Answer:
Option (1)
Step-by-step explanation:
Equation of the given wave function,
f(x) = acos(bx)
Here, a = amplitude of the wave
Period of the wave =
From the graph attached,
Amplitude =
=
= 4
Period of the wave = π - 0
= π
From the formula of the period,
Period =
b = 2
Therefore, a = 4 and b = 2.
Option (1) will be the answer.
Answer:
(-1,9)
Step-by-step explanation:
y = -3x + 6
y = 9
-3x + 6 = 9
-3x = 3
x = -1
y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,
-3(-1) + 6 = 9
(-1,9)
