Answer:
f(x) = x² - 81 = ( x+ 9)(x - 9) Difference of two squares
g(x) = x+9/x-9
g(x) . f(x) = x + 9/ x - 9 × (x+9)(x - 9)
= ( x + 9)(x +9)
= ( x + 9)²
= x² + 18x + 81
Hope this helps.
Linear line formula: y = mx + b
m = slope
b = y-intercept
In this case the question gives us what we need to substitute.
m = 4
b = 3
y = 4x + 3
