According to the given data we have the following function:
g (x) = 3x^2 + 2x - 4
To find g (1.5) we would need to substitute the variable x with the number 1.5 and then we would solve the expression above.
So, g (1.5)=3(1.5)^2 +2(1.5) -4
g (1.5)=6.75 + 3 -4
g (1.5)=5.75
Therefore, g (1.5) would be 5.75
