There is a great website called Desmos. You can enter any equation and it wil graph it for you.
You would just write f(x) (f of x) in for y: f(x) = 7x + 8.
Hope it helps.
Answer:
D: 64 x^27 y^125
Step-by-step explanation:
You can use either a calc or your knowledge of cube roots. I will be using knowledge.
You can automatically <em>rule out</em> a and b as if you take the cube root of 12, no whole number comes out. You are left with c and d. Option D is correct because the cube root of 64 is a whole number (4), the cube root of 27 is a whole number (3), and the cube root of 125 is also a whole number(5).
