The answer would be Addition property of equality i belive
Answer:
The correct option is;
Substitute x = 0 in the function and solve for f(x)
Step-by-step explanation:
The zeros of a function are the values of x which produces the value of 0 when substituted in the function
It is the point where the curve or line of the function crosses the x-axis
A. Substituting x = 0 will only give the point where the curve or line of the function crosses the y-axis,
Therefore, substituting x = 0 in the function can't be used to find the zero's of a function
B. Plotting a graph of the table of values of the function will indicate the zeros of the function or the point where the function crosses the x-axis
C. The zero product property when applied to the factors of the function equated to zero can be used to find the zeros of a function
d, The quadratic formula can be used to find the zeros of a function when the function is written in the form a·x² + b·x + c = 0
X^2-4x=0
Let x=0
0^2=4(0)=0
0=0 [checks out]
and
x^2-4x=0
(4)^2-4(4)x=0
16-16=0
0=0 [also checks out]
∛x-1+3 = 0
Add -3 to both sides to give ∛x-1 = -3.
Now cube both sides to give x - 1 = -27. Add 1 to both sides to find x, which is -26.
55-46.75= 9.25
the sales discount is $9.25
