No.
f(x) = 2*(x-3)*(x+2)/(x-1) for x ≠1
3.
y = 5x + 3When x=2,y = 5(2) + 3 = 10 + 3 = 13
It is used in hyperbolic functions; it's the rule to change a normal trig function into hyperbolic trig function. Example: cos(x-y) = cosx cosy + sinx siny Cosh(x-y) = coshx coshy - sinhx sinhy Whenever you have a multiplication of sin, you write the hyperbolic version as sinh but change the sign. also applied when: tanxsinx (sinx)^2 etc... Hope this helps you
Something like "Write a false statement".
y = 2, 4, 6, 8
y = 8 - 2*x
The function rule for this is (1) it is a variable or phantom any letter that stands on its own is a phantom here is a example =Y(2x + 2x)=2=2=4x + Y=5 (I am a grade 8 i know how you feel)
x + y = -2 y = -x - 2 f(x)= - x -2
The answer is A = 2.

g = f(x) = 3x + 2
Yes.
A polynomial of degree 2.
Yes, y=-2+x is a linear function.
