The value of the expression 7d²+10 is 73 if the value of d is 3, 7d²+10 represents a function in terms of d which gives a value of 73 when we put d = 3
It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have an expression 7d²+10
Let's denote it with f(d)
f(d) = 7d²+10
If d = 3 then the value of the expression is, simply put d = 3 in the above expression:
f(3) = 7(3)²+10
f(3) = 7×9 + 10
f(3) = 63+10
f(3) = 73
Thus, the value of the expression 7d²+10 is 73 if the value of d is 3, 7d²+10 represents a function in terms of d which gives a value of 73 when we put d = 3
