Answer:
Step-by-step explanation:
![x\le -4\\ \\ g(-4)=\sqrt[3]{-4+5}\\ \\ g(-4)=\sqrt[3]{1}=1](https://tex.z-dn.net/?f=x%5Cle%20-4%5C%5C%20%5C%5C%20g%28-4%29%3D%5Csqrt%5B3%5D%7B-4%2B5%7D%5C%5C%20%5C%5C%20g%28-4%29%3D%5Csqrt%5B3%5D%7B1%7D%3D1)
You start off by multiplying the second bracket by -1 to get rid of the bracket.
So,
(2x3 + x2 - 4x) - 9x3 + 3x2 =
2x3 +x2 - 4x - 9x3 + 3x2 =
(2x3 - 9x3) + (x2 + 3x2) - 4x =
-7x3 + 4x2 - 4x
Answer:
The slope of the line can be determined from the gradient equation, rise (y axis)/ run (x-axis)
Hence let (-1, 8) be A and (2, -4) be B. The slope from A to B is (-4-8)/(2-(-1))= (-12)/3= -4
Hence the gradient/ slope of the line is -4.
