Which of the following is the reciprocal parent function A.f(x)= -x^2 B.F(x)= x+1 C. F(x)=|x| D.F(x)=1/x
2 answers:
Answer: The correct option is D.
Explanation:
The reciprocal function is in the form of rational function and negative exponent form.
The parent equation of reciprocal function is,
It can be written as,
The domain of this function is all real numbers except 0 and range is all real number except zero.
Therefore, the correct option is D.
The function in option A and B are polynomial functions.
The function in option C is a modulus function.
Therefore, the options A,B and C are incorrect.

<u>Answer:</u>
The maximum number of turkey sandwiches Ben could have sold is 6.
<u>Step-by-step explanation:</u>
We are given that turkey sandwiches cost $2.50 and veggie wraps cost $3.50 at a snack stand.
Given the information, we are to find the maximum value of turkey sandwiches Ben could have sold.
Number of veggie wraps sold (y) = 4
2.50x + 3.50(4) < 30
2.50x + 14 < 30
<u> - 14 -14 </u>
2.50x < 16
The maximum number of turkey sandwiches Ben could have sold is 6.
Answer:
The second option
Step-by-step explanation:
The given system of equation is
x+2y=3
-x+y+z=2
y-2z=-3
The augment matrix is obtained by combining the coefficient matrix with the constant matrix to obtain;
Note that the absence of z, in the first equation means its coefficient is zero. The same thing applies to x in the last equation.
The correct choice is the second option.
