- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
When we graph the equation, we should see that our y-values span from -∞ to 0. Since 0 is a closed dot, it is inclusive in the range:
(-∞, 0] or y ≤ 0
Answer:
Step-by-step explanation:
Los movimientos bancarios de Santiago se representan matemáticamente teniendo en cuenta que consignar es sumar y retirar el restar. Por lo tanto podes expresar los movimientos bancarios de la siguiente manera:
- Lunes → + 300.000
- Martes → -120.000
- Miércoles → -95.000
- Jueves → +80.000
Al realizar la sumatoria se obtiene:
+300.000 - 120.000 - 95.000 + 80.000 = + 165.000
En la semana Santiago obtiene en su cuenta bancaria $165.000
Average time of a commuter train trip from one town to the city = 77 minutes
Time taken by 1 trip = 71 minutes
Time taken by another trip = 74 minutes
Time taken by 3rd and 4th trip each = 78 minutes
Let us assume the time taken during the 5th trip = x
Then
(71 + 74 + 78 +78 +x)/5 = 77
301 + x = 77 * 5
301 + x = 385
x = 385 - 301
= 84 minutes
So the length of the fifth trip was 84 minutes. I hope the procedure is clear enough for you to understand.
A.) 33.3% _
1 divided by 3 = 0.3 and if you multiply it by 100 it equals 33.3%
A linear function graphs as a line, and is written in the form f(x)=mx+b, with m being the slope and b being the y-intercept. A quadratic function can graph as any of the conic sections, including a parabola, hyperbola, ellipse, or circle. A quadratic function is a function in which the highest variable's power is exactly 2. The most commonly known quadratic function is a parabola, which has an increasing slope in one direction of the x-axis and a decreasing slope in the other. It is a curve that looks similar to a u, and it is written in the form f(x)=ax²+bx+c; c is the y-intercept, and the sign of a determines whether the curve opens up or down. An exponential function is often of the form f(x)=a^(bx)+c, and c can be any polynomial or constant. The function approaches a limit as x approaches infinity in one direction, and approaches infinity in the other direction, determined by the size of a and the sign of b. A straight line refers to a function of the form f(x)=c, c being a constant value.
