4,2 and 8 i'm pretty sure.
Answer: pink
Step-by-step explanation: bubblegum
Answer:
see below
Step-by-step explanation:
f(x) = 4x^2 + 8x − 5
To find the x intercepts set y = 0
0 =4x^2 + 8x − 5
Factor
0=(2x-1)(2x+5)
Using the zero product property
2x-1 =0 2x+5 =0
2x=1 2x = -5
x = 1/2 x = -5/2
The x intercepts are ( 1/2 ,0) and ( -5/2,0)
Rewriting in vertex form by completing the square
4 ( x^2 + 2x) -5
4 ( x^2+2x +1) -4*1 -5
4 ( x+1) ^2 -9
Vertex form is
a( x-h) ^2 +k where ( h,k) is the vertex
The vertex is ( -1,-9)
We know it opens upwards since a > 0
Plot the vertex and the x intercepts
The graph is symmetric on based on the vertex
Answer:
Graph A is a function, and Graph B is not
Step-by-step explanation:
A function is when each x-value (aka input) has 1 corresponding y-value (or output).
We see that graph 1 is linear, and that each x-value has it's own y-value, and not multiple y-values.
However, Graph B curves, making it so some of the x-values have more than 1 y-value.
Answer:
Brownies
18
54
270
Cooldies
16
32
96
384
Step-by-step explanation:
Brownies
simply multiply the 18 by 3 we get 54 and if we multiply 54 by 5 we get 270.
we multiply it by 5 because in series it skip 1 number to multiply next.
Cooldies
first we multiply 16 by 2 we get 32.
next we multiply 32 by 3 we get 96.
and next we multiply 96 by 4 we get 384.
Simply increment in multiplication.
