"zeros" of a function?

Question

1 define (a)algebraically ; (b) graphically

2 how does one find them?

Answer 1

zeros are for example:

(x-2)(x+2)

2 is the zero and -2 is a zero.

Answer 2

It is the value of x when y is 0

zeros on a graph are where the line/parabola/etc. cross the x-axis.

find them by...well should be kinda obvious now

Answer 3

1. (a) When y=0, then x=some value and that value is a zero of the function.

(b) Graphically when the function crosses the x-axis. If it crosses it twice then there are two zeros, etc.

2. You find them by solving the equation for x. The solution or solutions are the zeros of the equation.

Have a good day!

Answer 4

its where the equation equals 0

the x value where y equals 0

exp. y=x-2  answer: 2

when x equals 2 y equals 0

Answer 5

algebraically number, expressible by algebraic operations; opposed to TRANSCENDENTAL ALSO ALGEBRAICALLY is the adverb. Graphically-is the adverb of graphical

you can find both of then in the Webster's new college dictionary

Answer 6

yup
