Answer:
b=9
Step-by-step explanation:
move the 4b over to the other side by adding it to both sides


F(x)=x2 + 2x - 5 represents a quadratic function
So 3+5=8
8+7=15
15+9=24
24+11=35
35+13=48
therefore
0+3=3
so therefore the answer this is a difficult question but the answer is kind of like whatever you added to n in the last term add two to that and add to your number to get that

Answer:
Option B. The equation has a maximum value with a y-coordinate of -21.
Step-by-step explanation:
The correct quadratic equation is

This is a vertical parabola open downward (the leading coefficient is negative)
The vertex represent a maximum
Convert to vertex form
Factor -3

Complete the square


Rewrite as perfect squares

The vertex is the point (2,-21)
therefore
The equation has a maximum value with a y-coordinate of -21
