let g(x)=-x^2+5x+3. find and simplify g(1/2)
Substitute 1/2 for x in the equation. Thus:
g(1/2) = (1/2)^2+5(1/2)+3
Then, evaluate the right side of the equation to get a value for g(1/2)
Going term by term, (1/2)^2 = 1/4
5(1/2) = 2 1/2
So, g(1/2) = 1/4 + 2 1/2 + 3
Adding the terms on the right side,
g(1/2) = 5 3/4
