Answer:
Explanation:
The range of the sin(x) function is -1 ≤ y ≤ 1, because the output of the sin(x) function oscillates between -1 and 1 regardless of the input 'x' value.
The range of a function represents the set of all possible output (y) values that the function can produce. The sine function, sin(x), oscillates between -1 and 1. This is because the maximum height a sine wave can reach is 1 (at π/2 and its equivalents) and its minimal height is -1 (at 3π/2 and its equivalents). Therefore, no matter what value of 'x' you insert into the sin(x) function, the maximum and minimum values for the output 'y' is 1 and -1 respectively. Hence, the correct answer is -1 ≤ y ≤ 1.

Answer:
B.one
Step-by-step explanation:
there is only one solution to the problem.
What is the equation of the line, in general form, that passes through the point (1, 1) and has a y-intercept of 2.
9 (x +2) < 3(3-5)
Step-by-step explanation:
9x+18 < 9-15
1)9-15= -6
9x+18 < -6
9x+18= -5
9x= (-5) - 18
9x= -23
x= 23/9=2 5/9
X=2,55556
Answer:
The solution of the system of the equation is (2, 2)
Step-by-step explanation:
Let us solve the system of equations
∵ 3x + y = 8 ⇒ (1)
∵ 3x - y = 4 ⇒ (2)
→ Add equations (1) and (2) to eliminate y
∴ (3x + 3x) + (y + -y) = (8 + 4)
∴ 6x + 0 = 12
∴ 6x = 12
→ Divide both sides by 6 to find x
∵
∴ x = 2
→ Substitute the value of x in equation (1) to find y
∵ 3(2) + y = 8
∴ 6 + y = 8
→ Subtract 6 from both sides
∵ 6 - 6 + y = 8 - 6
∴ y = 2
∴ The solution of the system of the equation is (2, 2)
