Answer:
The answer is option C
Step-by-step explanation:
f(x) = x³ + 2x² + 3x + 4
To find f(-1) substitute the value of x that's
- 1 into f(x)
That's
<h3>

</h3>
We have the final answer as

Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7

Answer:
A and C
Step-by-step explanation:
Nothing much, just add 2 1/2 to 3 2/3 and subtract 2 1/2 from 3 2/3
Answer:

Step-by-step explanation:
f(x) = 2x + 6
f(-19) = 2*(-19) + 6
= -38 + 6
= -32
