The top number is 4 and t =1, so you need to replace t with 1, find the answer, then replace t with 2 through 4, then find the sum of all of them:
6^1-1 = 6^0 = 1
6^2-1 = 6^1 = 6
6^3-1 - 6^2 = 36
6^4-1 = 6^3 = 216
Sum = 1 + 6 + 36 + 216 = 259
The answer is B.
Answer:
Step-by-step explanation:
f(x) = x² is an up-opening parabola with vertex (0,0). There is one x-intercept, and that is the vertex.
g(x) = x²-7 is the equivalent to f(x) shifted down 7 units. Since the vertex is below the x-axis and the parabola opens upwards, it intercepts the x-axis at two points.
