PLEASE HELP TIMED QUIZ!

smaller (t) = 2 and this in coordinates form (2,0)

larger (t) = 15 and this in coordinates form (15,0)

the vertex of the parabola =   or in decimals (8.5, 42.25)

Step-by-step explanation:

SMALLER (t):

(t-2)=0

(add 2 for both sides)

t=2

LARGER (t):

(t-15)=0

(add 15 for both sides)

t=15

step1: expand the brackets:

f(t)=-(t-2)(t-15)

f(t)=

step2: define a,b and c using the expression :

a= -1 (the coefficient of )

b= 17 (the coefficient of t)

c= -30 (the single number without a letter)

step3: sub the values in the formula to find the x coordinate of the vertex :

=

= or in decimals 8.5

step4: sub the value of t (the x-coordinate) in equation f(t):

f(t)=

f ( )  = - + 17× - 30

= + -30

= or in decimals 42.25
