y=-x^2 +7
The range is the possible values of y for all acceptable values of x.
In this case x can be anything, so at its smallest value of 0, y=7, and at its largest value of infinity, y=negative infinity, so the range is negative infinity to 7.
The domain is from negative infinity to positive infinity. The range is from positive 2 to positive infinity.
x2+2x+1=y or y=x2 In this function the domain is x equals real values and the range is y equals all real values provided y is more than or equal to zero.
The domain and range can be the whole of the real numbers, or some subsets of these sets.
The range is y >= 5.
The range depends on the domain, which is not specified.

The range is y >= 5.
The domain is all real numbers, and the range is nonnegative real numbers (y ≥ 0).
The range depends on the domain, which is not specified.
It depends on the domain and codomain. In complex numbers, that is, when the domain and codomain are both C, every quadratic always has an inverse.If the range of the quadratic in the form ax2 + bx + c = 0 is the set of real numbers, R, then the function has an inverse if(a) b2 - 4ac ≥ 0and(b) the range of the inverse is defined as x ≥ 0 or x ≤ 0
It is y >= 5.
All real numbers that are greater than or equal to zero
The function y=x is a straight line. The range is all real numbers.
No, the range of a quadratic function is not all real numbers. A quadratic function, typically in the form ( f(x) = ax^2 + bx + c ), has a parabolic shape. If the coefficient ( a ) is positive, the range is all real numbers greater than or equal to the minimum point (the vertex), while if ( a ) is negative, the range is all real numbers less than or equal to the maximum point. Thus, the range is limited to values above or below a certain point, depending on the direction of the parabola.
If the domain is the real numbers then so is the range.
