Please see the pic, I'd solved your question in it.
Answer:
Step-by-step explanation:
Answer:
odd function
Explanation:
To determine if a function f(x) is even/odd consider the following.
• If f(x) = f( -x) , then f(x) is even
Even functions are symmetrical about the y-axis.
• If - f(x) = f(-x) , then f(x) is odd
Odd functions have symmetry about the origin.
Test for even function
f(−x)=4(−x)3=−4x3≠f(x)
Since f(x) ≠ f( -x) , then f(x) is not even
Test for odd function
−f(x)=−(4x3)=−4x3=f(−x)
Since - f(x) = f( -x) , then f(x) is odd
graph{4x^3 [-10, 10, -5, 5]}
So.... notice the picture below
now, we know what the "height" or "altitude" is
now, we also know the perimeter is 18cm
so, k + k + b = 18
or 2k + b = 18
thus

so... one can say that

and you can simplify it if you wish.. not sure you have to

fill the dot for including equality
point to left for "smaller than"
