Answer:
f(-8) = -512, f(8) = 2
Step-by-step explanation:
Substitute x = -8 and 8 into the function, taking into account the rules of the function.
For x = -8, x < 0 so the value is equal to the cube of -8, which is -512.
For x = 8, x > 0 so the value is equal to the cube root of 8, which is 2.
Answer:
Step-by-step explanation:
Given that,
A line 7x - 3y = 68 and containing the point (8, -8).
The equation can be written as :
The slope is :7/3
Line is perpendicular so use m = –3/7
So, required equation is :
