The option (D) the graph crosses the x-axis at the point (2, 0) is correct because the graph crosses x-axis at points (0, 0), (5, 0), (-2, 0), and (2, 0).
<h3>What is a function?</h3>It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The correct question is in the picture please refer to the attached picture.
We have a function:
f(x) = x⁴ - 5x³ - 4x² + 20x
By using factorization method:
By using zero product rule:
x = 0
x = 5
x = -2
x = 2
The graph crosses the x-axis at points (0, 0), (5, 0), (-2, 0), and (2, 0)
Thus, the option (D) the graph crosses the x-axis at the point (2, 0) is correct because the graph crosses the x-axis at points (0, 0), (5, 0), (-2, 0), and (2, 0).

Answer:
see explanation
Step-by-step explanation:
(a ) calculate the slope m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = A(0, 6) and (x₂, y₂ ) = B(3, 0 )
=
=
= - 2
(b)
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
(c)
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
(0, 6 ) is the y-intercept ⇒ c = 6
y = x + 6 ← equation of perpendicular line
