Answer:
Step-by-step explanation:
This is more easily understood if you take out a common factor of -1
-1(x^2 + 15x + 56)
7*8 = 56
7 + 8 = 56
-1 (x +8)(x+7)
Answer:
all possible input values to the function
Step-by-step explanation:
The domain is the input to the function and the range is the output of the function
Answer:
d
Step-by-step explanation:
Answer:
They all are polynomials.
Step-by-step explanation:
Given : Following expression
1) 
2) 
3) 
4) 
The following all are polynomials because polynomials are:
An expression consisting of variables and coefficients or expression more than two algebraic terms and the terms that contain different powers of the same variable(s) involve operations addition , subtraction, multiplication and non-negative integer exponent of variables.
So when we see to these functions they all are a mixture of a polynomial.
