Answer:
f(x) = |x|
Step-by-step explanation:
Only f(x) = |x| is an even function. If you evaluate this function at x = 3, for example, the result is 3; if at x = -3, the result is still 3. That's a hallmark of even functions.
Answer:
a^3 + b^2
Step-by-step explanation:
Let's simplify step-by-step.
a^3+b^2
There are no like terms.
Answer:
=a^3+b^2
The answer is 10 because 1 divided by 10 is 0.1 then times that by 10 and you get 1.
Xy=yz: if you divide each side by y, you get: xy/y=yz/y; so x=z.
Since x=z, if you multiply both variables by the same number, they will still equal. Let this number be y: xy=zy.
Hope this hels! :)
