Given:
The graph of a function.
To find:
The function.
Solution:
From the given graph, it is clear that the graph intersect the x-axis at x=-4, -2, 1. It means -4, -2 and 1 are zeros of the given function graph.
If c is a zero of a function f(x), then (x-c) is a factor of f(x).
Using the above definition, we conclude that (x+4), (x+2) and (x-1) are the factors of given function. So,
Therefore, the correct option is A.
Answer:
(1, 3)
Step-by-step explanation:
Given coordinates of 2 endpoints, G(-2, 5) and H(4, 1), midpoint of AB is calculated as shown below:
Midpoint (M) of GH, for G(-2, 5) and H(4, 1) is given as:
Let
Thus:
Coordinates of the midpoint of GH = (1, 3).
The values of (x, y) are (-5, 1), if the equations and
are solved by elimination method.
Step-by-step explanation:
The given is,
................................(1)
.....................................(2)
Step:1
Equation (2) is multiplied by -1 ( Eqn (2) × -1 )
..................................(3)
Step:2
Substrate the equation (1) and equation (3),
( - )
After the Subtraction equation becomes,
Step:3
By using y value find value of x,
Step:4
Check for solution,
Both sides are equal so answer is corrected
Result:
The values of (x, y) are (-5, 1), if the equations and
are solved by elimination method.
