The function best represented by the graph is y = <u>- 5 x + 5 2y = - 5 x + 5²</u>. Option B.
Use the vertical line test to determine if a graph represents a function. A graph is a function if a vertical line moves across it and touches it only at one point at a time. If a vertical line touches a graph at multiple points, the graph is not a function.
Calculation:-
X intercept = 2
y intercept = 5
slopt = y/x
= 5/2
= 2.5
For the line to be perpendicular to each other angle must be 90⁰.
Hence option B.
B.y = - 5 x + 5
2y = - 5 x + 5 2
slope m = 5/2
2.5.
A function is defined as a relation between a set of inputs each with an output. Simply put, a function is a relationship between inputs, each associated with exactly one output. Each function has a domain and a codomain or scope. The graph of a quadratic function is called a parabola and has a curved shape. One of the main points of the parabola is the vertex.
