consider the function g(x)=x^3+5x^2-4x+4.determine:
2)the value of x between zero and a hundred such that g(x)=145456
how do i do this?
1) put in 37 for x, and compute.
2) put in 145456 in for g(x), and solve for x.
for the first one, just substitute 37 for x and evaluate
for the second one
x^3 + 5x^2 - 4x + 4 = 145456
x^3 + 5x^2 - 4x - 145452 = 0
at this point you will need a programmable calculator which solves any equation, or
use Newton's Method, or
go to an online "equation solver"
I went to
and it gave me an exact value of x=51
