Answer:
Part 1)
Part 2)
Step-by-step explanation:
we have
![f(x)=\sqrt[3]{x} +1](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%5B3%5D%7Bx%7D%20%2B1)
Part 1) Find f(125)
we know that
f(125) is the value of the function f(x) when the value of x is equal to 125
so
For x=125
substitute in the function
Remember that

substitute
Applying the power of rule
![\sqrt[3]{5^{3}}=(5^{3})^{\frac{1}{3}}= (5)^{3*\frac{1}{3}}=5](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5%5E%7B3%7D%7D%3D%285%5E%7B3%7D%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%3D%20%285%29%5E%7B3%2A%5Cfrac%7B1%7D%7B3%7D%7D%3D5)
substitute
Part 2) Find f(-64)
we know that
f(-64) is the value of the function f(x) when the value of x is equal to -64
so
For x=-64
substitute in the function
Remember that

substitute
Applying the power of rule
![\sqrt[3]{-4^{3}}=(-4^{3})^{\frac{1}{3}}= (-4)^{3*\frac{1}{3}}=-4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-4%5E%7B3%7D%7D%3D%28-4%5E%7B3%7D%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%3D%20%28-4%29%5E%7B3%2A%5Cfrac%7B1%7D%7B3%7D%7D%3D-4)

Answer:
$7.39
Step-by-step explanation:
False, 2/6 is less than 2/3
A pound of rice crackers ... $2.88
1/4 pound of crackers ... $x = ?
If you would like to know how much did Matthew pay for the crackers, you can calculate this using the following steps:
1 * x = 1/4 * 2.88
x = 1/4 * 2.88
x = $0.72
Result: Matthew paid $0.72 for 1/4 pound of crackers.
