Answer:
Only the second one represent a function because the x does not repeat.
For the first and last functions the x is repeating; therefore they are not functions.
Answer:
(0,4) and (-2,0)
Step-by-step explanation:
y=3x²+4x+4
y = -2x +4
3x²+4x+4 = - 2x +4
3x²+6x=0
3x(x+2)=0
x=0, x= -2
x=0, y=-2x+4= -2*0 + 4 =4, (0,4)
x= - 2, y = 2x + 4= 2*(-2) +4=0, (-2,0)
When you draw a horizontal line through the given solution point, you find it intersects the unit circle at 150°. Thus the appropriate choice for the remaining solutions will be
... 30° + n•360°, 150° + n•360°
A is unsolvable because 4=0.
B can be solved.
C is infinite
