1/5*82/10=82/50

82/10-82/50

=820/100-164/100

Consider the functions f(x) = x2 − 13 and g(x) = x + 5. What is the value of (f − g)(−4)? ...?

Answers

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

f(x) = x2 - 13
g(x) = x + 5

and are asked to compute "f-g" when x=-4. there are two ways of doing this. you can either first find f(-4) and g(-4) and then substract one from other like so:

f(−4)=(−4)2−13=16−13=3
g(−4)=−4+5=1

f(−4)−g(−4)=3−1=2

or you can create a new function that represents "f-g", call it "h", and work out h(-4) as follows:

h(x)=f(x)−g(x)=(x2−13)−(x+5)=x2−13−x−5=x2−x−18
h(−4)=(−4)2−(−4)−18=16+4−18=2
