Directions: Using the integers -9 to 9, at most one time each, fill in the boxes to create a logarithmic function with the greatest possible y-intercept.
Hint
How do each of the values you can choose affect the values of the y-intercept?
Answer
The greatest possible y-intercept is 9 and can be gotten from an equation like:
y = 4 * log2(x – (-8)) + -3
y-intercept: 9
