<span> f (x)= 10-x³.
f(2) means the value of the function when x=2.
So, we need to substitute 2 instead of x.
f(2) = 10 - 2³ = 10-8 =2
f(2) = 2

Check the picture below, keeping in mind that opposides sides and interior angles in a parallelogram are congruent.
The 7 is in the Ones place
Answer:
3
Step-by-step explanation:
because it tje best answer on there ferl me
The differnce quotient is basically taking the derivitive (result will be f'(x)=5, but anyway)
here is the disffernce quotient
![lim_{h\rightarrow0}\frac{f(x+h)-f(x)}{h}](https://tex.z-dn.net/?f=lim_%7Bh%5Crightarrow0%7D%5Cfrac%7Bf%28x%2Bh%29-f%28x%29%7D%7Bh%7D)
so
for your equation
![lim_{h\rightarrow0}\frac{(5(x+h)+4)-(5x+4)}{h}](https://tex.z-dn.net/?f=lim_%7Bh%5Crightarrow0%7D%5Cfrac%7B%285%28x%2Bh%29%2B4%29-%285x%2B4%29%7D%7Bh%7D)
![lim_{h\rightarrow0}\frac{5x+5h+4-5x-4}{h}](https://tex.z-dn.net/?f=lim_%7Bh%5Crightarrow0%7D%5Cfrac%7B5x%2B5h%2B4-5x-4%7D%7Bh%7D)
![lim_{h\rightarrow0}\frac{5h}{h}](https://tex.z-dn.net/?f=lim_%7Bh%5Crightarrow0%7D%5Cfrac%7B5h%7D%7Bh%7D)
h's cancel and you are left with 5
the differnce quotient is 5
