<span>The equation given is f(x) = x^2 - 12x + 27
</span>
Based on its form, it is a parabola. First, factor the quadratic equation:
f(x) = (x-9) (x-3)
Plot in the x-y plane, assign values of x and solve for the values of y.

Answer:
Surface area = 90 cm²
Step-by-step explanation:
Given net of the rectangular prism shows the dimensions as,
Length = 5 cm
Width = 5 cm
Height = 2 cm
`Expression for the surface area of a rectangular prism = 2(lb + bh + hl)
Here, l = length
w = width
h = height
By substituting the values in the expression,
Surface area = 2(5×2 + 5×2 + 5×5)
= 2(10 + 10 + 25)
= 90 cm²
