3.70 was the tax price

To find the sales tax, you would subtract that from the total price. If the book was $40 you would subtract that from $43.70. 
$43.70 - $40 = $3.70

Your answer would be $3.70

I hope this helps!

F(x) = x^2. What is g(x)?
Flauer [41]

Answer:

Third option.

Step-by-step explanation:

The coordinates are (1, 3)

x = 1

y = 3

Put x as 1, the output should be 3.

g(1) = 3(1)²

g(1) = 3(1)

g(1) = 3

Please help me find out what the question marks are
quester [9]
Question a

g(x) times \sqrt{x-5}=\sqrt{x^2-5}
divide both sides by √(x-5)
g(x)=\frac{\sqrt{x^2-5}}{\sqrt{x-5}}
g(x)=\frac{(\sqrt{x-5})(\sqrt{x^2-5})}{x-5}
g(x)=\frac{\sqrt{x^3-5x^2-5x+25}}{x-5}


question b
g(x) \space\ times \space\ 1+\frac{1}{x}=x
divide both sides by 1+1/x
g(x)=\frac{x}{1+\frac{1}{x}}
times by x/x
g(x)=\frac{x^2}{x+1}


question c
\frac{1}{x} \space\ times \space\ f(x)=x
times both sides by x
f(x)=x^2


question d
the (f*g)(x) collumn seems to have a domain of only x is greater than or equal to 0?
so maybe we squared the whole thing, ya
wait
ah, ya
basically
|x|=(\sqrt{x})^2=(\sqrt{x})(\sqrt{x})
so f(x)=√x


a. g(x)=\frac{\sqrt{x^3-5x^2-5x+25}}{x-5}
b. g(x)=\frac{x^2}{x+1}
c.f(x)=x^2
d. f(x)=\sqrt{x}
