Answer:
f(10)=290
Step-by-step explanation:
Function Evaluation
Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.
We are given the function:
[tex]f(x)=3x^2-x[/tex]
It's required to find f(10). We replace the x for 10:
[tex]f(10)=3*10^2-10[/tex]
Operating:
[tex]f(10)=3*100-10[/tex]
[tex]f(10)=300-10[/tex]
[tex]f(10)=290[/tex]
Thus, f(10)=290
