Answer:
"Aperture" seems to be the right answer.
Explanation:
- The intensity of light rays that enters an electronic camera sensor is limited either by an aperture. This same diameter would be determined by f-stops.
- This opens with a smaller f-stop level which accommodates sufficient light to something like the sensor. Relatively high f-stop amounts reduce their aperture of the lenses so that less beam moves.
The correct answer for, find F(-4). F(x) = 2x^2 - x + 9 is 45
Kinda confused but only did it for points sooo
