f(x) maps vales in the domain to values in the range, using the given rule. So, to find f(1/4), replace all the x's with 1/4:
f(1/4) = 2(1/4)^2 + 2
Now just simplify that.
what is the value of the range of the function f(x)=x^2+2 for the domain value 1/4?
How do I solve? Please don't just straight up give me the answer >.< I want to know how to do this.
