b

Answer 2

\(\large\color{black}{ \displaystyle g(x)=x^2+3 }\)
if I wanted to find \(g(5)\) i would simply plug in 5 for x. This way:
\(\large\color{black}{ \displaystyle g(\color{red}{5})=\color{red}{5}^2+3 }\)
\(\large\color{black}{ \displaystyle g(5)=25+3 }\)
\(\large\color{black}{ \displaystyle g(5)=28 }\)

Answer 3

Way of getting answer is substitute the values your are given in position of x and then calculate.
Example; 1) g(x)=x2+3

Answer 4

thnx :)

Answer 5

TO find g(4), all you got to do is to plug in 4 instead of x, just the same way as i did with g(5).
