The function ƒ(x) = x is transformed to g(x) = 2x. What type of transformation has occurred? A/ Reflection
B/ Rotation
C/ Vertical translation
D/ Can't be determined

B) Rotation

Step-by-step explanation:

The only difference between functions f(x) and g(x) is the slope. To get from f(x)=x to g(x)=2x, you would need to rotate slightly counter-clockwise about point (0,0) - the origin/y-intercept. This would make the graph steeper (2x is steeper than x) while still retaining the (0,0) y-intercept.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
