Ok so first, you can take out a greatest common factor, which is 2
You’ll be left with 2(x^2-3x-20)
I factored from there
Here’s my work
Hope this helps :)
F(5)= 17
We want to plug in 5 for x into the equation.
f(x) = 3x +2
f(5) = 3(5) +2
=15 +2
=17
Yes it has a fraction on 2.88888/1 <span> = 28.8888/10 = 288.888/100 = 2888.88/1000 = 28888.8/10000 = 288888/100000</span>
