Answer:
Vertex → (2, 4)
Step-by-step explanation:
Quadratic equation has been given as,
y = -x² + 4x
We rewrite this equation in the form of a function as,
f(x) = - x² + 4x
By comparing this equation with the standard quadratic equation,
y = ax² + bx + c
a = -1 and b = 4
Vertex of the parabola represented by this equation is given by
x coordinate =
= 2
y-coordinate = f(2)
= - (2)² + 4(2)
= -4 + 8
= 4
Therefore, vertex of the given function is (2, 4)
Answer:
The Two points for the line are
point A( x₁ , y₁) ≡ ( 0 , 4)
point B( x₂ , y₂) ≡ (8 , 0)
The Graph is attached below.
Step-by-step explanation:
Given:
........... equation of a line Given
Let the points be point A, and point B
To Find:
point A( x₁ , y₁) ≡ ?
point B( x₂ , y₂) ≡ ?
Solution:
For Drawing a graph we require minimum two points but we will have here.
For point A( x₁ , y₁)
Put x = 0 in the given equation we get
∴ point A( x₁ , y₁) ≡ ( 0 , 4)
For point B( x₂ , y₂)
Put y= 0 in the given equation we get
∴ point B( x₂ , y₂) ≡ (8 , 0)
Therefore,
The points for the line are
point A( x₁ , y₁) ≡ ( 0 , 4) (blue color point on the graph)
point B( x₂ , y₂) ≡ (8 , 0) (green color point on the graph)
The Graph is attached below..
