Apolynomial function has roots –5 and 1. which of the following could represent this function? f(x) = (x + 5)(x + 1) f(x) = (x – 5)(x – 1) f(x) = (x – 5)(x + 1) f(x) = (x + 5)(x – 1)

f(x) = (x + 5)(x - 1)

using the ' factor theorem '

given x = a is the root of a polynomial then (x - a ) is a factor

here roots are x = - 5 and x = 1 hence factors are (x + 5) and (x - 1)

the polynomial is the product of the factors

f(x) = (x + 5)(x - 1)

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

r and t.

both are 64 degrees.
