In the function y+2=1/3(x-4)^2

Mathematics
1 answer:
Ivenika [448]3 years ago
3 0

Answer:

The negative 4 translates the original function 4 units horizontally to the right

Step-by-step explanation:

The transformed graph is  y+2=\frac{1}{3}(x-4)^2

and the parent function is  y=x^2

We need to find what effect does the "4" in the transformed function have with respect to the parent function. Lets look at a general form of a transformed quadratic function and see what each variable means:

y+b=a(x-c)^2

This is the general form.

  • +b means the graph is vertically translated b units down
  • -b would have meant the graph would have been vertically translated b units up
  • a transforms the parent by vertically stretching or compressing
  • -c means the parent is shifted c units right
  • +c would have meant the parent will be shifted c units left

In our transformed graph, we have a "-4", this means, according to the rules above, that:

the parent function is shifted 4 units to the right

What is the domain and range for the following function and its inverse?
Basile [38]

Answer:

"f(x)  

domain: all real numbers, range: all real numbers  

f–1(x)  

domain: all real numbers, range: all real numbers"

Step-by-step explanation:

We can use the fact that the domain of a function and the range of its inverse are equal.

Also, the range of the function and the domain of its inverse are equal as well.

<em>Looking at the function f(x/ = -x + 5, we see that this is a line with a negative slope of 1 and a y-intercept of +5. </em>

As we know from the graph of lines, there is no restricting values in x and y. So for the original function,  domain is the set of all real numbers and the range is the set of all real numbers.

For the inverse, the range is set of all real numbers and domain is also the set of all real numbers.

First answer choice is right.
