no, but y = x2 is a function
y is greater than 0
X is greater than or equal to 2. The symbol for "greater than or equal to" is a "greater than" sign over a horizontal dash.
' x ' = any whole number greater than ' 2 '.
(f-1)'=2+2x,x is greater than or equal to zero and f'(2)=3,find f'(x)
If the domain for f(x) is all real numbers greater than or equal to 2, it means that the function is defined for any input x that is 2 or higher. This implies that any x-value less than 2 is not part of the function's domain. Consequently, f(x) may involve operations such as square roots or logarithms that restrict the inputs to this interval. Thus, the function's behavior and outputs are only considered for x-values starting from 2 onward.
f(x) = (x)^ (1/2) (i.e. the square root of x)
Only if the discriminant of its equation is greater than zero will it have 2 different x intercepts.
An exponential function of the form a^x eventually becomes greater than the similar power function x^a where a is some constant greater than 1.

The two are equal at three points: x = -0.766 664 7.., x = 2 and x = 4. For x < -0.766 644 7.., x2 is greater For -0.766 644 7.. < x < 2, 2x is greater For 2 < x < 4, x2 is greater For 4 < x, 2x is greater
Yes!!! It is '5'. Remember 4 x 5 = 20 2 x 2 x 5 = 20 20
The real numbers greater than or equal to -2, represented by {x: x >= -2 }, is a set. A set is simply a group of things, which you can ask if a particular element is in that set. For example, 17.273 is in {x: x >= -2}, but "apple" is not in {x: x >= -2}. In this case, the set {x: x >= -2} contains all the real numbers that are greater than or equal to -2 and nothing else.
The function ( f(x) = x^2 + 5 ) is a quadratic function that opens upwards, with its minimum value occurring at the vertex. The vertex is at the point (0, 5), which is the lowest point on the graph. Since ( x^2 ) is always non-negative, the function's output will always be greater than or equal to 5. Therefore, the range of the function is ( [5, \infty) ).
