The domain is from negative infinity to positive infinity. The range is from positive 2 to positive infinity.
The function ( f(x) = x^2 ) is a quadratic function that opens upwards. Its range is all non-negative real numbers, starting from 0 to positive infinity. Therefore, the range can be expressed as ( [0, \infty) ).
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 function ( y = x^2 ) is a quadratic function that opens upwards. Its range is all non-negative real numbers, starting from zero to positive infinity. Therefore, the range can be expressed as ( y \geq 0 ) or in interval notation as ( [0, \infty) ).
The range of a cubic parent function, which is defined as ( f(x) = x^3 ), is all real numbers. This is because as ( x ) approaches positive or negative infinity, ( f(x) ) also approaches positive or negative infinity, respectively. Therefore, the function can take any value from negative to positive infinity. In interval notation, the range is expressed as ( (-\infty, \infty) ).

Integers are whole numbers that go from negative infinity to positive infinity. As such, they do cover the negative range of the number line.

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.
The function ( f(x) = \log_2(3x + 4) ) has a range of all real numbers. As ( x ) approaches (-\frac{4}{3}) from the right, ( f(x) ) approaches negative infinity, and as ( x ) increases, ( f(x) ) approaches positive infinity. Therefore, the range is ( (-\infty, \infty) ).
The domain and range can be the whole of the real numbers, or some subsets of these sets.
Both extend from negative infinity to positive infinity.
The range of a function when you consider a graph is how high and how low it goes. A quadratic function is usually an arch that goes up to a high point and then back down like the arch of a kicked ball. Or, it can be the reverse which goes down and then up in a mirror image of a kicked ball. The range is what y values would be needed to show ALL the graph. Example; y=x^2+5x-6 The graph crosses the x axis at -5 and 1 it goes down then back up. The range is from infinity down to -49/4
