Factor x2 – 3x – 28.
wariber [46]

Values needed to complete the X diagram are:

On top -28, On the bottom: -3 and On the sides: -7 and 4.

<h3>What do you mean by factorization?</h3>

An algebraic expression is factorised when it is written as the product of its factors.

The given equation is :

F(x) = x²-3x-28

finding factors,

=  x²-7x+4x-28

= x(x-7) +4(x-7)

= (x-7)(x+4)

Given general equation is ax²+bx+c,

on comparing with  x²-3x-28

a = 1

b = -3

c = -28

ac = 1*(-28) = -28

Population growth is:<br> A) Logarithmic<br> B) Linear<br> C) Exponential<br> Please help ASAP!!! :(
Monica [59]

For this case we have that by definition the growth of a population is a function of the form:

f (x) = a (b) ^ x

Where,

  • <em>a: initial population </em>
  • <em>b: growth rate </em>
  • <em>x: number of years </em>

We observe then that the function is of the exponential type.

Answer:

C) Exponential
