if f(x) varies directly with x2 and f(x)=10 when x=−4 , what is the value of f(x) when x = 3?
−14.4

−5.625

5.625

14.4

you need to show us the graph.

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)
