F(x) = 4x - 9
let f(x) = y, this implies that x = f⁻¹(y)
y = 4x - 9 Let us solve for x.
4x - 9 = y
4x = y + 9
x = (y + 9)/4
Recall that x = f⁻¹(y),
x = (y + 9)/4
f⁻¹(y) = (y + 9)/4
That means that for f⁻¹(x)
f⁻¹(x) = (x + 9)/4
Hope this explains it.
Vertical asymptotes can be found by setting the denominator equal to 0
x^2-6x = 0
factor out x
x(x-6)
set the two parts equal to 0
x = 0
x-6 = 0
x = 6
so the two x values are 0 and 6
ANSWER: B. x = 0, x = 6
For 1 kilometer, the customary measure is 62/100 miles. The easiest way to think about this is to forget that the units are miles. Instead think of it as money. If I have $1 that means I have 100 out of 100 cents. So if I have 50 cents my fraction is 50/100; and the way we write this is 0.50... if I have 32 cents then my fraction is 32/100 and we write this as 0.32. So if you have 62 cents out of a 100, how would you write that in decimal form?

That's math for you.
