If you vertically stretch the linear parent function f(x)=x, by a factor of 2, what is the equation of the new function?
1 answer:
Answer:
y=2x
Step-by-step explanation:
The condition about stretching is that when the stretch factor is greater than 1, the function will be closer to OY axis; when the stretch factor is between 0 and 1, the function will be closer to OX axis.
We can observe this end result in the attached graphs.
The red line represent the original function and the blue line is y=2x
As we can observe that the condition still holds.

The length of the hypotenuse is 6√2 units.
Answer:
Step-by-step explanation:
By the negative exponent rule, you have that:
By the exponents properties, you know that:
Therefore, you can rewrite the left side of the equation has following:
Descompose 32 and 8 into its prime factors:
Rewrite:
Then:
As the base are equal, then:
Solve for x:
