Based on the graphed values of f(x) and independent variable x, the graph shows that C. k is greater than zero.
What is the value of k?
We have a c value of -1 which is where the y axis is intercepted.
We know that k isn't zero because the x and y values are not the same. We can also tell that k is not less than 0 because if it was, the f(x) for the smaller x value would lead to a larger f(x) value.
The only logical conclusion therefore, is that k is greater than zero.
