Answer:
a v-shaped graph with a minimum at (-2,-1) and x-intercepts at -1 and -3
Step-by-step explanation:
if you need to graph the function then start by creating an x-y table of values:
when x=0, y=1
so you the point: (0, 1)
when x=2, y=3
you have another point: (2,3)
when x=-2, y = -1
third point: (-2,-1)
when x=-3, y = 0
fourth point: (-3,0)
Answer:
A
Step-by-step explanation:
The equation will be in the form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (2.5, 0) ← 2 points on the line
m =
= - 2
The line crosses the y- axis at (0, 5) ⇒ c = 5
y = - 2x + 5 or
y = 5 - 2x → A

Step-by-step explanation:
i beieve this is the answer dont be mad if its not
Firstly you have to multiply both sides by 2 to get rid of the fractions. This leaves you with x + 18= 8. If you take away 18 from both sides you can see that x = -10
