Answer:

Step-by-step explanation:

y = 3x - 4

x = 0, y = 3*0 - 4

y = -4

(0 , -4)

x = 1 , y = 3*1 - 4

y = 3 - 4

y = -1

(1 , -1)

x = 2 , y = 3*2 - 4

y = 6 - 4

y = 2

(2 , 2)

Now mark these points (0 , -4) , (1 , -1) & (2 , 2) in the graph and join the points

Answer:

Step-by-step explanation:

$\text{Use}\ \log_ab=c\iff a^c=b,\ \text{for}\ a>0,\ b>0\ \wedge\ a\neq1\\\\Domain:b>0\ \wedge\ b\neq1\\\\\log_b(512)=3\iff b^3=512\to b=\sqrt[3]{512}\\\\\begin{array}{c|c}512&2\\256&2\\128&2\\64&2\\32&2\\16&2\\8&2\\4&2\\2&2\\1\end{array}\\\\512=2^9=2^{3\cdot3}=(2^3)^3=8^3\\\\\text{Therefore}\ b=\sqrt[3]{512}=\sqrt[3]{8^3}=8\in D$
