No i am pretty sure it is
Answer: No, x+3 is not a factor of 2x^2-2x-12
========================================================
Explanation:
Let p(x) = 2x^2 - 2x - 12
If we divide p(x) over (x-k), then the remainder is p(k). I'm using the remainder theorem. A special case of the remainder theorem is that if p(k) = 0, then x-k is a factor of p(x).
Compare x+3 = x-(-3) to x-k to find that k = -3.
Plug x = -3 into the function
p(x) = 2x^2 - 2x - 12
p(-3) = 2(-3)^2 - 2(-3) - 12
p(-3) = 12
We don't get 0 as a result so x+3 is not a factor of p(x) = 2x^2 - 2x - 12
----------------------------------------
Let's see what happens when we factor p(x)
2x^2 - 2x - 12
2(x^2 - x - 6)
2(x - 3)(x + 2)
The factors here are 2, x-3 and x+2
Hi,
If it is f(x)=2x²+3 and not F(x)=2x²+3 then
Answer D.
The corresponding values needed will be -23, -8, 7 and 22
<h3>Functions and Tables</h3>
Given the function y = 5x - 8
<h3>Get the domains and range</h3>
We are to get the range of the function for the given domains
If the value of x is -3
y = 5(-3) - 8
y = -15 - 8
y = -23
If the value of x is 0
y = 5(0) - 8
y = 0 - 8
y = -8
If the value of x is 3
y = 5(3) - 8
y = 15 - 8
y = 7
If the value of x is 6
y = 5(6) - 8
y = 30 - 8
y = 22
Hence the corresponding values needed will be -23, -8, 7 and 22
