Assuming the ':' means an = sign, 2
=10 simplifies to 2
=8
Answer:
98
Step-by-step explanation:
As it is a little bit of a few questions about the other one I have to the store go back tomorrow and will get back tomorrow and I have been working
There is a hole at x=4 because the top factors to (x-4)(x+3)
in the end we get
f(x)=(x-4)(x+3)/(x-4)
the (x-4) cancels out and we get
f(x)=x+3
so baiscally f(x) is y=x+3 but with a hole at (4,7)
one way is to make a piecewise function defined as(x^2-x-12)/(x-4) for all x≠4 and defined as 7 for x=4
or, to just do f(x)=x+3
