We can see that
There are four triangle on the surface
and five squares
For finding surface areas , we will find area of each surface and then add them
Calculation of area of triangle:
We are given
base=b=8
height=h=10
now, we can use area formula
Calculation of area of square:
base=width=8
There are four triangle and five squares on the surface
so, we can find surface area
SA=4* triangle + 5*square
so, surface area is

Hey buddy whatsup? All good
Coming to the question fig 1 and 3 aren't functions
Coz.... Reason for fig 1... Every distinct element of domain must have a unique element in codomain, but in this fig the same element has more than two unique elements which is a relation not a function.
Reason for fig 3 every element in domain must have an unique element in codomain but in this fig the element c doesn't have any unique element hence it isn't a function.....
Thank you
90% = 90/100 = 9/10 = 0.9
Hope this helps :)
A) Growth: f(x) because it is getting larger exponentially due to an integer greater than 1 being raised to an exponent.
b) Decay: g(x) because it is getting smaller exponentially due to an integer less than 1 being raised to an exponent.
c) Have the lead exponent being not equal to 1.
d) Whether or not the number being raised to the exponent is greater than or less than 1.
e) f(x) because it is an exponential growth function, which none of the others are.
