Question

What is a quartic function with only the two real zeros given?

x = -4 and x = -1

Answer 1

Just punch in the values given for x into each function, and which ever one returns 0 for both values of x satisfies the condition.

so for example:

(-4)^4+5(-4)^3+5(-4)^2+5(-4)+4=

256-320+80-20+4=0

And (-1)^4+5(-1)^3+5(-1)^2+5(-1)+4=

1-5+5-5+4= 0
