Answer:
The car travels different distances per unit of time because the portion shows a nonlinear, increasing function; -50; Both Table A and Table B do not represent functions; −2 ; {−2, 0, 1, 2, 3, 4}
Step-by-step explanation:
A linear graph of any sort is a graph that has a constant rate of change. This graph is not linear; therefore it does not have a constant rate of change. This means that the car travels different distances per unit of time between sections.
To find the rate of change, we find the slope between these two points. We use the formula
Using our points, we have
A function is a relation in which each element of the domain (x) is mapped to only one element of the range (y). In both of these tables, we have x-values that are mapped to two y-values; in Table A, 3 is mapped to 1 and 0; and in Table B, 5 is mapped to 2 and -2.
We use the slope formula again:
Using our points, we have
The domain of a graph is the set of inputs or x-values. From our points, we have the set:
{-2, 0, 1, 2, 3, 4}
Answer:
x = - 7, x = 1
Step-by-step explanation:
Given
x² + 6x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 7 + 9
(x + 3)² = 16 ( take the square root of both sides )
x + 3 = ± = ± 4 ( subtract 3 from both sides )
x = - 3 ± 4
x = - 3 - 4 = - 7
x = - 3 + 4 = 1
Solution set = { - 7, 1 }
