Are you factoring or simplifying?
Answer:
Domain: All Real numbers
CoDomain : All Real numbers
Range:
; that is: Real numbers larger than or equal to zero
Step-by-step explanation:
Notice that the graphed function can use any Real number x (from - infinity to + infinity) and produce an output. Therefore, the Domain of the function plotted in graph 3 is : All Real numbers.
The set of possible outputs (CoDomain) is also the set of all Real numbers (notice that the y-axis extends form - infinity to + infinity
But the Range (the actual set of the collection of outputs of the function) is just a subset of the CoDomain consisting of the Real numbers larger than or equal to zero (notice that the drawing of the function touches the x axis and lies completely on the upper half of the plane.
Step-by-step explanation:
5x - 7 = 13
5x = 13 + 7
5x = 20
x = 20 ÷ 4 = 5
10x - 14
10(5) - 14 = 50 - 14 = 36
Y = (x - 3)² + 53
y = (x - 3)(x - 3) + 53
y = (x(x - 3) - 3(x - 3)) + 53
y = (x(x) - x(3) - 3(x) + 3(3)) + 53
y = x² - 3x - 3x + 9 + 53
y = x² - 6x + 62
Consumption per 14 Mile/gallon. OR 14 MPG
Distance is = Number of gallons in the tank x MPG
Let y = distance and x = the number of gallons, then:
y= x.(MPG). (MPG is a constant)
Apply it to the given data: MPG = 14 and x = 22 gallons,
y= 22.(14) = 308 miles
