Answer:
Step-by-step explanation:
Given the equation of a line expressed as y = 3x-1, we are to find y = f(x) for the following values of x in the table.
If y = 3x-1, then f(x) = 3
When x = -1
f(-1) = 3(-1)-1
f(-1) = -3-1
f(-1) = -4
<em>Hence when x = -1, f(x) = -4</em>
<em></em>
When x = 0
f(0) = 3(0)-1
f(0) = 0-1
f(0) = -1
<em>Hence when x = 0, f(x) = -1</em>
<em></em>
When x = 2
f(2) = 3(2)-1
f(2) = 6-1
f(2) = 5
<em>Hence when x = 2, f(x) = 5</em>
I believe the answers are:
-3/2
-7/2
Answer:
Step-by-step explanation:
85=2x(x^2+3)(2x+5)
85=2x(2x^3+5x^2+6x+15)
85=4x^4+10x^3+12x^2+30x
4x^4+10x^3+12x^2+30x-85=0
2x^2(2x^2+5x+6)+30x-85=0
shoot, this isn't possible with quadratic, maybe you can get somewhere from here
Should be 10, or 9.65606. Hope this helps!
