Answer:
5
Step-by-step explanation:
f(x) = 2x - 3x + 7
Plug in 2 every time you see an x within the equation: x = 2
f(2) = 2(2) - 3(2) + 7
f(2) = 4 - 6 + 7
f(2) = -2 + 7
f(2) = 5
Here, you have to determine values of f(x) for negative domain. Domain are those values of x for which function is defined.
Since the function is a polynomial, every value of x∈R is defined for f(x).
And for every negative value of x, f(x) will always be positive because x is squared and square of negative real number is always positive.
0 is neither negative nor positive. Therefore, zero is not included in negative domain. If you plug say x= -0.00000956, f(x) will be greater than 1 because square of x will never be negative.
Thus, the range will always be positive or greater than equal to 1.
Therefore, y≥1
