Answer:
x = 0
Step-by-step explanation:
When there is no linear term in the equation, the axis of symmetry is x=0.
__
The values 'a' and 'c' represent a vertical scale factor and a vertical translation, respectively. They do not change the axis of symmetry from that of the parent function, which is x=0.
Answer:
A, C, E
Step-by-step explanation:
Substitute the x- coordinate of the points into the equation and if the result is equal to the y- coordinate of the point then it is a solution.
A (- 2, 5 )
y = 2² + 1 = 4 + 1 = 5 → (- 2, 5 ) is a solution
B (- 1, 0 )
y = (- 1)² + 1 = 1 + 1 = 2 ≠ 0 ← not a solution
C (1, 2 )
y = 1² + 1 = 1 + 1 = 2 → (1, 2 ) is a solution
D (2, 4 )
y = 2² + 1 = 4 + 1 = 5 ≠ 4 ← not a solution
E (3, 10 )
y = 3² + 1 = 9 + 1 = 10 → (3, 10 ) is a solution
Answer:
Rural and urban settlements are interdependent by : -Economic activities of rural agriculture,livestock,fishing serve as the raw materials for vast segments of industries established in urban areas. -development in urban areas in terms of better roads,railways has helped in connecting many rural areas with urban areas.Rural-urban dependence implies joint or interactive relation between the urban and rural areas.Both are interdependent on each other.
