let f(x) be a cubic polynomial with zeros -5,4 and 5. If the graph of f passes through the point (0,25) write the complete factored form of f(x)
type your answer in factored form
----
f(x) = a(x+5)(x-5)(x-4)
---
Solve for "a" using (0,25)
---
25 = a(5)*(-5)(-4)
25 = a*100
a= 1/4
---
Equation:
f(x) = (1/4)(x+5)(x-5)(x-4)
