Answer:
N times 4-1
Step-by-step explanation:
4 times number is not a squared number where you multiply- the number
by it's self and then you subtract 1
19 + 14 + 10 = 43
just sub in the numbers into the equation to replace the X ..
example for
a) h(7) : 44
h(7) : x^2 -5
sub in 7 into the equation to replace X
so you get
(7)^2 - 5
49-5
44
