Answer:

Rahm: 0.8

Bain: 1.2

Step-by-step explanation:

For this, they ask for the rate of change or slope. To find slope you can use slope formula to get your slope/rate of change.

Steps for Rahm:

We can take points (10,8) and (20,16) and find the slope with the following formula: $\frac{y^2-y^1}{x^2-x^1}$

$\frac{16-8}{20-10} = 0.8$

This is the rate of change for Rahm

Steps for Bain:

Take the points (5,6) and (11,13.2) and plug them into the Slope Formula:

$\frac{13.2-6}{11-5} = 1.2$

Therefore, Bain hiked faster than Rahm for he had the higher rate of change compared to Rahm.

I need help with this function

viva [34]

$f(x)=3x^2+1\\
g(x)=2x+2\\\\
y=2x+2\\
2x=y-2\\
x=\dfrac{1}{2}y-1\\
g^{-1}(x)=\dfrac{1}{2}x-1\\\\
(f\cdot g)(x)=f(x)\cdot g(x)\\\\
(f\cdot g^{-1})(2)=(3\cdot2^2+1)(2\cdot2+2)\\
(f\cdot g^{-1})(2)=(12+1)\cdot6\\
(f\cdot g^{-1})(2)=13\cdot6\\
(f\cdot g^{-1})(2)=78
