consider the function:

f(x) =

what are these values?

f(-3)=-2.5 ,

f(-1)=1.5 ,

f(3)=0.75

Step-by-step explanation:

f(-3) means find the value of function f(x) when x=-3

from given restriction we see that x=-3 lies withing

corresponding function value is

So plug x=-3 into

-------

f(-1) means find the value of function f(x) when x=-1

from given restriction we see that x=-1 lies withing

corresponding function value is

So plug x=-1 into

-------

f(3) means find the value of function f(x) when x=3

from given restriction we see that x=3 lies withing

corresponding function value is

So plug x=3 into

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
