Question

A function f(x) has range ( y ∈ ℝ , | , -50 < y ≤ 0 .

A. f(x)=2x+10
B. f(x)=−3x²+5
C. f(x)= √x−8
D. f(x)= 1/x

Answer 1

The function that satisfies the given conditions is f(x) = x².

Step-by-step explanation:

The function that satisfies the given conditions is B. f(x) = x². This is because the function has a positive value at x = 3, and its slope is decreasing in magnitude with increasing x.

The graph of this function is a parabola that opens upward.
