Answer:
Yes it is.
Step-by-step explanation:
When we mix Fe(iron) to CuSO⁴ (Copper sulphate), Iron removes copper from CuSO⁴ and makes FeSO⁴. This happens because iron is more reactive than copper. We cannot remove iron from this solution now until any stronger element is added.
Answer:
the above is a function
Step-by-step explanation:
function is a mapping from a set A to B, which associative every element of A with unique image in B.
Here, f(-3)=6, f(-5)=6
f(3)= -2, f(-5)=1
all elements have image.
so this is a function.
Answer:
f(3) = -16
Step-by-step explanation:
f(1) = -16
f(n) = f(n-1)
f(2) = f(2-1) = f(1) = -16
f(3) = f(3-1) = f(2) = -16
