Answer: New function is
Step-by-step explanation:
- A dilation is a transformation that creates an image using a scale factor that has the exactly same shape as the original, but have a different size.
The given function :
We know that any function y= f(x) will become y=k f(x) after dilation of k units on the x, where k= scale factor for dilation.
Here, the given scale factor = 2 i.e. k=2
Then, the new function will be :
Hence, the new function is
Answer:
C
Step-by-step explanation:
from some other question so thank this guy
Frika
1. C
becasue there are no repeating x values in a function.
2. A
because the values of f(X) are always 5 more than the values of x.
hope this helps!
Answer:
cm/sec.
Step-by-step explanation:
We have been given that a particle in the first quadrant is moving along a path described by the equation such that at the moment its x-coordinate is 2, its y-coordinate is decreasing at a rate of 10 cm/sec. We are asked to find the rate at which x-coordinate is changing at that time.
First of all, we will find the y value, when by substituting in our given equation.
Since the particle is moving in the 1st quadrant, so the value of y will be positive that is .
Now, we will find the derivative of our given equation.
We have been given that , and .
Therefore, the x-coordinate is increasing at a rate of cm/sec.
Answer:
x ≥ -4
Step-by-step explanation:
4x+5 ≤ 2x-3
Collect like terms
4x-2x ≤ -3-5
Simplify
2x ≤ -8
Divide both sides by 2
2x / 2 ≤ -8 / 2
x ≥ -4
