If f(x)=3/x+2 - sqrt x-3, complete the following statment f(19)=

A function is just a rule of associations, telling you how to deal with every (feasible) input.

In this case, writing

means that, whenever a number is given as input, the correspondent output will be computed as the rule states: you divide 3 by that input plus two, and then you will subtract the square root of the input, minus 3.

So, if we're asked for a specific value, we have to perform this instructions, using 19 as input:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
