Answer:
D. G(x) = 7x2
Step-by-step explanation:
Given a function f(x), the function kf(x) is stretched by a factor of k. In this case, if we stretch the function f(x) = x^2 by a factor of 7, the new function is going to be:
g(x) = 7x^2. Therefore, the correct option is option D.
Step-by-step explanation:
B: The x axis is the horizontal one. If we look at the graph, there are actually two spots where the line crosses the x axis. It looks to be between -2 and -1 as well as 1 and 2
D: For vertical parabolas such as this, the axis of symmetry is the x coordinate of the vertex. The vertex is essentially the middle point, that, for this graph, is at the bottom. The axis of symmetry is x=0 as that is the x coordinate of the vertex.
E: f(x), in 2D graphs, is typically y, as is the case here. As this parabola opens upward, the minimum point is the vertex, which seems to be -3 for this graph. As the graph seems to be x²-3 or something like that, there is nothing limiting x from being infinity, and when x is equal to infinity in this function, y is as well. Thus, the maximum is infinity.
Answer:
Probability that the randomly selected two students both have no loans to pay = 0.09
Step-by-step explanation:
Probability that a student has a loan to pay is 0.7, hence probability that a student has no loan to pay is
1-0.7 = 0.3
Probability that the randomly selected two students both have no loans to pay = 0.3 × 0.3 = 0.09
