Answer:

See below

Step-by-step explanation:

I assume you mean f(x) = 3(x-1)^2-4

The equation is already in vertex form f(x)=a(x-h)^2+k where a affects how "fat" or "skinny" the parabola is and (h,k) is the vertex. Therefore, the vertex is (h,k)\rightarrow(1,-4).

The axis of symmetry is a line where the parabola is cut into two congruent halves. This is defined as x=h for a parabola with a vertical axis. Hence, the axis of symmetry is x=1.

The minimum value is the smallest value in the range of the function. In the case of a parabola, the y-coordinate of the vertex is the minimum value. Therefore, the minimum value is y=-4.

The interval where the function is decreasing is (-\infty,1)

The interval where the function is increasing is (1,\infty)

A 6 cm long spring extends to 9 cm when a 1 kg load is suspended from it. What would be its length if a 2 kg load were suspended
vampirchik [111]

Answer:

12 cm

Step-by-step explanation:

To calculate the length of a spring with a 2 kg load, compare the displacement of a 1 kg load and adjust accordingly.

When a 1 kg load is suspended from the spring, the spring which is 6 cm stretches to 9 cm. This is 3 cm longer due to the weight. If you attach a weight which is twice as much then the displacement will be twice as much. Instead of stretching an additional 3 cm, it will stretch 2*3 = 6 cm. Add this to the length of the spring and it stretches in total 6 + 6 = 12 cm.
