The graph of y = (-3x)^2 is much narrower than it's original graph, but still keeps all of the other properties of it's parent parable y = x^2. The new graph's with is that of the original parabola's with divided by 3.
Answer:
all real numbers or ![(-\infty, \infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20%5Cinfty%29)
Step-by-step explanation:
since both f(x) and g(x) are polynomials, neither of them have restrictions on their domains. Since they can be defined for all real numbers. It's not like the square root which has a domain of (0, infinity), or log x which is defined only from (0, infinity). So adding these two polynomials would result in a domain of all real numbers.
Step-by-step explanation:
Use formula to find the slope/gradient
![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
(-5, -1) = (x1, y1)
(5, 11) = (x2, y2)
So,
![= \frac{11 - ( - 1)}{5 - ( - 5)} \\ = \frac{12}{10 } \\ = \frac{6}{5}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B11%20-%20%28%20-%201%29%7D%7B5%20-%20%28%20-%205%29%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B12%7D%7B10%20%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B6%7D%7B5%7D%20)

y=f(x) is in function notation
Answer:
-2.26 lb
Step-by-step explanation:
Let the dog's initial weight be d.
Then, one year later, the dog weighs 3.73 lb less, and thus weighed d - 3.73 lb.
During the next year, the dog gained 1.47 lb, so now weighs d - 3.73 + 1.47 lb, or
d - 2.26 lb. This indicates a total weight loss of 2.26 over these two years.
