357/4 is the answer I'm not sure
Answer: #4 C Domain is x such that x is greater than -1 (all real numbers greater than -1)
#5 B Points C, F & G
Step-by-step explanation: Look at the coordinate of the vertex. It is at (-1, 1) so the -1 is the lowest number in the Domain (running left to right). The attows at the right ends mean that the lines go to infinity. The symbol ∈ means "belongs to" the R (special font not available here) means "all real numbers.
The y-value, 1 is not relevant here, as the Range (up and down, like a mountain range) is infinity, and the arrows keep going forever. ∈R means all real numbers.
For the Triangle, first imagine a box with the boundaries matching the domain and range given, so the left side is at -2, the right side is at 6 [Domain] and the top and bottom are at 5 and -1 [Range]
Pick the points that are on the boundary lines. C is at (6,3) on the right boundary, F is at (2,-1) on the bottom boundary and G is at (-2,5) at the corner where the top and left sides meet.
a) the general equation for this table is -5x + 6 (y int=6)
b) is saying you have a function f(x)= 2x + 10. When x = 0, y = 10
c) the statement tells you already that the y intercept is 6
d) if you study the graph, at x = 0, y = 4.
Therefore, d) has the smallest intercept a y = 4.
Let’s first expand out before factorising completely.
(2a + 2b) (2a + 2b) =
4a^2 + 8ab + 4b^2
Add to 4b^2 - a^2
4a^2 + 8ab + 8b^2 - a^2
= 3a^2 + 8ab + 8b^2
=8b (a + b) + 3a^2
=8b (a + b + 3a^2/8b)
=8b (b+ a(1+3a/8b))
This might be wrong lol.
