1.) Without the use of a graphing calculator or other graphing technology, identify the zeros of the
polynomial function P(x) = 2(x + 2)(x + 1). Show how you calculated the zeros in the space
below. Then use the zeros to sketch the graph of P.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
