Answer:
its A
Step-by-step explanation:
f(x) = 2x^2 - 4x - 3; opens up; vertex: (1, -5); y-intercept: (0, -3)
g(x) = -x^2 + x + 1; opens down; vertex: (0.5, 1.25); y-intercept: (0, 1)
h(x) = -2x^2 + 3x - 1; opens down; vertex: (0.75, 0.125); y-intercept: (0, -1)
m(x) = x^2 - 9; opens up; vertex: (0, -9); y-intercept: (0, -9)
n(x) = -3x^2 + 7; opens down; vertex: (0, 7); y-intercept: (0, 7)
I have attached an image of the functions and their graphs.
Hope this helps!
Answer:
The smallest number is 23
Step-by-step explanation:
Let x be the first number
x+1 is the next consecutive number
x+2 is the next consecutive number
The sum is
x+ x+1 + x+2 = 72
Combine like terms
3x+3 = 72
subtract 3 from each side
3x+3-3 = 72-3
3x = 69
Divide each side by 3
3x/3 = 69/3
x = 23
x+1 = 24
x+2 =25
The numbers are
23,24,25
Answer:
translation of 2 unit(s) left and a reflection across the x-axis
Step-by-step explanation:
B' is 2 units left of B.
The triangle is exactly across the middle, or the x-axis.
Answer: Not enough information
Step-by-step explanation:
You never gave enough information. All we got is that y = 3x. If I at least knew what y was, then I could divide it by 3. Can you at least edit the question with what equals y?
