Question

f(x)=-4xto the power of 2 what is the range

Answer 1

Answer:

(-infinity, 0]

Step-by-step explanation:

I'm assuming you meant  f(x) = -4x^2.  If so, the graph is that of a parabola that opens down and has vertex at (0, 0).  In other words, f(x) is always zero or below zero.

Thus the range is (-infinity, 0]
