The function appears to be L(legos) = T(tower)^3

L = T^3

This checks out for t =1,2,3,4

The 100th tower would have 100^3 legos.

100^3 = 1,000,000.

The 100th tower would have 1 million cubes

If f(x) =3x-5 them find values of f(3) and f(-7). please explain step by step​
LenKa [72]

Answer:

f(3) = 4

f(-7) = -26

Step-by-step explanation:

Hi there!

f(x) =3x-5

To find f(3), replace every x with 3:

f(3) =3(3)-5\\f(3) =9-5\\f(3) =4

Therefore, f(3)=4.

f(x) =3x-5

To find f(-7), replace every x with -7:

f(-7) =3(-7)-5\\f(-7) =-21-5\\f(-7) =-26

Therefore, f(-7)=-26.

I hope this helps!
