Question

WILL GIVE BRAINLIEIST!!

Answer 1

Answer:

The matches are:

Feature: Increasing or decreasing interval (specifically, a decreasing interval)

Statement: As the input power's current grows beyond 1 ampere...

Feature: Relative minimum or maximum (specifically, relative maximum)

Statement: At its most efficient, the motor uses...

Feature: x-intercept

Statement: The motor loses all efficiency when the current...

Step-by-step explanation:

The first statement describes a decreasing interval, specifically the decreasing efficiency beyond 1 ampere of input current

The second statement describes a relative maximum, specifically the maximum efficiency at an input current of 1 ampere

The third statement describes an x-intercept, specifically the efficiency hitting 0% when the input current is ≥ 3 amperes

Answer 2

Answer:

(a) x -intercept with the last statement (the one at the bottom)

(b) Relative maximum with the second (middle) statement.

(c) Increasing or decreasing with the first (top) statement.

See details below:

Step-by-step explanation:

(a)  The x-intercept goes with the info on what happens when the graph crosses the horizontal axis, so it goes with the third statement given:

The motor loses all efficiency when the current hits 3 amps.

(b)  Relative max: agrees with what happens at the maximum the curve shows reaching approximately 50% value in the vertical scale:

At its most efficiency the motor uses about 50% of the  input power

(c)  Increasing or decreasing interval: The function clearly increases from values of the horizontal variable starting at around 0.4, up to a value of 1, and from then onwards it decreases. So it agrees with:

As the input grows more than 1 ampere, the motor becomes less efficient.
