Answer:
c. f(x) = (x + 4)(x - 1)
Step-by-step explanation:
Since you're familiar with the product of two binomials:
(x +a)(x +b) = x² + (a+b)x + ab
you know that the constants in the binomial factors must ...
- have a product of -4
- have a sum of +3
__
All of the choices except B have binomial constants that have a product of -4.
In order, the sums of the remaining choices are ...
A: 1-4 = -3
C: 4-1 = 3 . . . . this is the correct choice
D: -2+2 = 0
f(x) is a linear function with no restrictions
Domain: x = All real numbers
Range: y = All real numbers
Answer:
it's b
Step-by-step explanation:
it's b because the lines outside of the equation mean the absolute value of the equation
Anything times 0 is 0
anything times 1 is the number the was multiplied <span />
