F(x)=2x+3
assuming the problem is 4 times 2 minus 2x plus 1
you add like variables
Answer: -9 = a(1 - 3)² + 3
Step-by-step explanation:
Vertex Form Equation:
y = a(x - h)² + k
vertex: (h, k) which means
h = 3
k = 3
because your vertex is (3, 3).
Your point is (1, -9) which is (x, y).
This means
x = 1
y = -9
Now, plug everything into your Vertex Form Equation:
-9 = a(1 - 3)² + 3
That’s your equation and final answer, but of course, if you need to, you can solve for a if you need to.
If a is positive, the parabola opens up. If a is negative, the parabola opens down.
Hope this helps!
45 times the numerator plus the denominator is most likely going to equal the same amount as if it were doubled.
The line is positive
The line is positive because it slants to the right.
It wouldve been negative if it slanted to the left.
