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
Answer:
x+y-5=0
Step-by-step explanation:
let eqn Perpendicular to eqn 5y-5x=-20 be -5x-5y+k=0------(1)
eqn (1) passes through (-3,8)
-5×-3-5×8+k=0
15-40+k=0
K=25
since required eqn perpendicular to 5y-5x=-20 is -5x-5y+25=0
x+y-5=0ans.
