First, a graph of f(x)=2x+1 is drawn. Then, three graphs of 2(x+k) are drawn, for k=1,2,3. Which will be true of these three graphs?
Their slops will be the same as the slope of f(x) and their x intercepts will be to the right of the x intercept of f(x)
Their slopes will be the same as the slope of f(x), and their x intercepts will be to the left of the x intercept of f(x)
Their slops will be different from the slope of f(x) and their intercepts will be to the right of the x intercept of f(x)
Their slopes will be different from the slope of f(x) and their x intercepts wille be to the left of the x intercept of f(x)
