2 Answer

1. User Answers mreijepatmat
f(x)=x³+5x²+1 . Just plug into the function x by its given value: x=3
f(x) = (3)³+5(3)²+1 ==> 27+45+1 ==>f(x) = 73

Answer:
F(x)=73
Stepbystep explanation:
Remember that to evaluate e afunction to a certain value you just need to insert value that your are given in the equation as "x":
[tex]f(x)=x^3+5x^2+1\\f(3)=(3)^3+5(3)^2+1\\f(3)=27+5(9)+1\\f(3)=27+45+1\\f(3)=73[/tex]
So the answer is that the function evaluated when x=3 is 73.
