Two functions are given below: f(x) and h(x). state the axis of symmetry for each function and explain how to find it.

Step-by-step explanation:

In each case, the axis of symmetry is the vertical line through the vertex.

For f(x)

The equation is in vertex form:

  f = a(x -h)² +k . . . . has vertex (h, k)

The x-coordinate of the vertex can be read from the equation: 4. The vertical line with that x-coordinate is ...

  x = 4

__

For h(x)

The vertex is the point where the graph reaches a maximum, (-2, 2). The vertical line with that x-coordinate is ...

  x = -2

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000
