a-b^2+4b+5 (2,) , ( ,2)
To find the value of the expression a-b^2+4b+5 at the points (2, ) and ( ,2), we need both the x and y coordinates for each point. The given points are (2, ) and ( ,2).
Let's start with the first point (2, ). To find the value of the expression at this point, we substitute the x-coordinate (2) into the expression:
a - b^2 + 4b + 5 = a - 2^2 + 4(2) + 5 = a - 4 + 8 + 5 = a + 9.
So, at the point (2, ), the value of the expression a-b^2+4b+5 is a + 9.
Now let's move on to the second point ( ,2). Since the x-coordinate is missing, we won't be able to calculate the value of the expression at this point without more information. If you provide the value of the x-coordinate for the second point, I can help you find the value of the expression at that point as well.
