The answer depends on the domain of f. With an unconstrained domain, the range is all real (or even complex) numbers.
y = 3x + 2x^2 + k where k is any number
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
4x + 3 doesn't factor. It is in its simplest form.
If the question gives 4x-3=9, then we can solve: 4x-3=9 4x=6 x=3/2, or 1.5
Is there an operator missing from this question? * 3 + 4x = 19 => x = 4 * 3 - 4x = 19 => x = -4 * 3 . 4x = 19 => x = 19/12

y = 3x + 2x^2 + k where k is any number
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
(4x2 - 13x - 12)/(4x+ 3) = (4x + 3)(x - 4)/(4x + 3) = (4x + 3)(x - 4)/(4x + 3) = x - 4 :)
The EPA range estimate for the 2013 Infiniti FX is 404.6 mi. in the city, 571.2 mi. on the highway.
The EPA range estimate for the 2012 Infiniti FX is 380.8 mi. in the city, 547.4 mi. on the highway.
The EPA range estimate for the 2011 Infiniti FX is 380.8 mi. in the city, 547.4 mi. on the highway.
4x + 3 doesn't factor. It is in its simplest form.
4x + 3 cannot equal 4x + 12:4x + 3 = 4x + 12 (given)3 = 12 (subtract 4x from both sides)
f(X)=4x+4 is the exact same thing as y=4x+4. it simply means the function of x is 4x+4. also, any other letter can be used in place of f. f(X)=4x+4 is the same as g(x)=4x+4.
x = ¼x^4 + 4x + k where k can be any number
(2x - 3)(4x + 9)(2x + 3) = (2x - 3)(2x + 3)(4x + 9) = [(2x)^2 - (3^2)](4x + 9) = (4x^2 - 9)(4x + 9) = (4x^2)(4x) + (4x^2)(9) - (9)(4x) - (9)(9) = 16x^3 + 36 x^2 - 36x - 81
