Answer:
<u>f(x) = x² - 4x + 2 or f(x) = (x - 2)²</u>
Step-b<u>y</u>-step explanation:
- The parabola touches the x-axis at only one point
- If we use y = a(x − h)² + k, we can see from the graph that h = 2 and k = 0
- This gives us y = a(x − 2)²
What is the value of "a"?
- We also see that the y-intercept is (0, 4)
- We can plug it into the equation
- 4 = a(0 - 2)²
- 4a = 4
- a = 1
<u>So, our quadratic equation will be</u> :
- y = 1(x - 2)²
- <u>y = x² - 4x + 2 or y = (x - 2)²</u>

Answer:
-3 - 1 = 4/9(-5 - 4)
Step-by-step Explanation:
Point-Slope form uses the formula y-y1=m(x-x1).
m is the slope, which they gave you, so you can substitute it into the formula:
y - y1 = 4/9(x - x1).
They also gave you a first point (-5, -3) So you can substitute the x and y of those into the formula as well.
-3 - y1 = 4/9(-5 - x1)
y1 and x1 are for another point. By drawing a graph and then using the rise and run of the slope (up 4 and over 9), you can get another point (as shown in the picture).
Substitute the x and y values of that point into the equation as well and you have your answer:
-3 - 1 = 4/9(-5 - 4)
Concentrate on the numbers alone. The GCF of 35, 14 and 63 is 7.
You know y^4 goes into every number, so that'll be in your answer as well.
The final answer would be 7y^4.
