Answer:
(3/2,11/4)
Step-by-step explanation
-b/2a to find the axis of symmetry
3/2= axis of symmetry
Then plug that in to find the vertex/maximum or minimum
3/2^2-3(3/2)+5
9/4-9/2+5
You can only add fractions with like denominators multiply 9/2(2/2) and 5(4/4)
So, 9/4-18/4+20/4
9/4-18/4= -9/4+20/4= 11/4
So the maximum is
(3/2, 11/4)
