Answer:
The domain is all real numbers greater than or equal to zero
Step-by-step explanation:
∵ f(x) = √9x
∴ The domain is all values of x ≥ 0
because if x = number less than zero it will be negative
There is no value in the real number for √-ve values
∴ The domain is all real numbers ≥ 0
Inverses
solve for x
replace x with f inverse
replace y with x
so
first minus 2 both sides
y-2=√(2x-3)
square both sides
y^2-4y+4=2x-3
add 3 to both sides
y^2-4y+7=2x
divide both sides y 2
(y^2-4y+7)/2=x
x turns to f inverse and y turns to x
f(x)⁻¹=

looks like they didn't want to expand the binomial
y=

answer si A
G(x) is the transformation of F(x) by
1. left shift by 4 unit
2. Vertical stretch by -1/2
If the ratio is 1:18, and we need to know how the other side for the ration 9:?, then we have to multiply 9x18.
9x18=162
so Laurel and Delmar are 162 km away
hope it helps! :3
