Question

What is a quart of function with only the two real zeros given? x = -4 and x = -1

Answer 1

f(x) =
`x^(2)+5x+4`

Explanation:

∵ The zeroes of the function are x = -4 and x = -1

∵ x + 4 = 0 and x + 1 = 0

∴ The factors of the function are (x + 4) (x + 1)

∴ The function = (x + 4) (x + 1)

∴ f(x) =
`x^(2)+5x+4`
