The range of which function includes -4
Answer:-
A) f(x)=2x+5
B) g(x)= √x+1
C) h(x)=x1?
D) k(x)=x2−4
D) k(x)=x2−4
The range of a function is the set of all possible output values that the function can produce for the given input values. In the case of the function k(x)=x2−4, let's analyze it.
The function is a quadratic function, and its output is determined by the square of the input (x2) minus 4. The constant term (-4) means that the minimum value of the function is -4. Therefore, any value less than -4 can be achieved as an output.
Thus, the range of the function k(x)=x2−4 includes -4, making option D the correct answer.
