i will brainlest first answer and no need for explanation

x - intercepts: -1, -7

Solutions: [is the x-intercepts] -1,-7

Factors: (x+1)(x+7)

Vertex: -4, -9

Axis of symmetry: x = -4

Step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
