F(x) = 3x² - 1
f(-2) = 3(-2)² - 1
f(-2) = 3(4) - 1
f(-2) = 12 - 1
f(-2) = 11
f(x) = x < 1
f(-2) = -2 < 1
f(x) = x + 2
f(-2) = -2 + 2
f(-2) = 0
f(x) = x > 1
f(-2) = -2 > 1
f(-2) = -2 < 1
Answer:
If you pick the number 2, you will get (2) - 10 = 8
But the way he said it, it would be: (2) - 2 * 5 = 0
The correct way would be to write the expression: (x - 3) * 5
y=kx
10=k15
<em>rearran</em><em>ge</em><em> </em><em>the</em><em> </em><em>eqn</em><em>,</em><em> </em><em>make</em><em> </em><em>k</em><em> </em><em>as</em><em> </em><em>a</em><em> </em><em>subj</em><em>ect</em>
k=10/15
k=2/3
Therefore, the answers
y=2/3x
