Option 2. shows the correct way to use the quadratic formula to solve the given equation.
Step-by-step explanation:
Step 1:
For an equation of the form the solution is
.
Here a is the coefficient of , b is the coefficient of x and c is the constant term.
can also be written as
Comparing with
, we get that a is 1, b is -4 and c is -21.
To get the solution, we substitute the values of a, b, and c in .
Step 2:
Substituting the values, we get
This is option 2.
You mean y = b^x.
By plugging different values of x, we find different y-values forming points in the form (x, y).
After 2 or 3 points, we can clearly see that the graph of y = b^x passes through the point (0, 1) and extends forever in the upward direction through quadrant 1.
