an expression is shown below:
f(x)=-16x^2+60x+16

part a: what are the x intercepts of the graph of f(x)? show your work. (2points)

part b: is the vertex of the graph of f(x) going to be a maximum of a minimum? what are the coordinates of the vertex? justifiy your answers and show your work.(3 points)

part c: what are the steps you would use to graph f(x)? justifiy that you can use the answers obtained in part a and part b to draw the graph (5 points)

answer: i believe its b. if you sound out the sentences that sounds wrong.

srry idk

step-by-step explanation:

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.

answer: b.36 feet
