The choices are supposed to be
f(x) = sin x + 3
f(x) = cos x + 3
f(x) = 3 sin x
f(x) = 3 cos x
The amplitude is the value of the numerical coefficient of sin or cos. The only possible answers are
f(x) = 3 sin x
f(x) = 3 cos x
Next, the function must pass through the point (0,3)
3 sin 0 = 0 and
3 cos = 3
Therefore, the answer is
f(x) = 3 cos x<span />
Answer:
12x
Step-by-step explanation:
Multiply 12 times another number.
2x + 30 = -20x + 8
2x + 20x = 8 - 30
22x = -22
x = 1
Answer:
11.x>50
12.y is greater than or equal to 8
15. z<8
