Help. after i post this i will have 2 points lwft
1 answer:
The slope is the ratio between the change in the y and x values. When you write a line as , the slope is the coefficient
. So, the slope of the first graph is 405, which means that the first plane flies with a speed of 405 miles per hour.
Similarly, from the table we can see that each time you increase x by 1, the distance traveled increases by 435. So, the slope of the second graph is 435, which means that the second plane flies with a speed of 435 miles per hour, and is thus faster.

Answer:
Option 2 is the answer.
Step-by-step explanation:
To find the equation for we will fist write the function in the form of equation.
y = √x +3
√x = y - 3
x = (y - 3)² = y² - 6y + 9
Now we will replace y as x to write inverse of function f(x).
We will rewrite the equation in the form of function.
= x² - 6x + 9 ≅ (x - 3)²
So the answer is = (x - 3)²
