Answer:
23
Step-by-step explanation:
Given : \(f(x)=4-x^2\)
\(g(x) = 6x\)
To Find: which expression is equivalent to (g – f)(3)?
Solution:
\(f(x)=4-x^2\)
\(g(x) = 6x\)
\((g-f)(x)=6x-4+x^2\)
Now substitute x = 3
\((g-f)(3)=6(3)-4+(3)^2\)
\((g-f)(3)=18-4+9\)
\((g-f)(3)=23\)
Hence the value of \((g-f)(3)\) is 23.
