Zeros

[JH_33]

The problem says to use a graphing utility to estimate the zero(s) of f(x)=x^3-5x+2. Im not sure what it means by etimate the zero(s) though?

Hello, JH_33!

The problem says to use a graphing utility to estimate the zeros) of f(x) = x³ - 5x + 2.

Im not sure what it means by estimate the zero(s) though

The "zeros" are the values of x which make the function equal to zero.
. . that is, the roots of x³ - 5x + 2 .= .0

Great, thanks for the help!

Either use a "solver" utility, or ZOOM in on the graph until you're really "close" to the x-intercept(s).
