I just need to know what this is asking me to do... I don't understand what it means by second point.. Use the parabola tool to graph the quadratic function.

f(x)=3x2+6x−24

Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.

the answer is 0.071

good luck! : d

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

i can answer this if i have the answer choices

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
