Answer:
c. 2/3
Step-by-step explanation:
Since the line is going up to the right it is a positive slope. Therefore it can't be a or d.
The slope is 2/3 because to connect the dots you have to go up 2 and to the right 3.
Hello : let : y = f(x) so : y' = f'(x)
calculate : f'(x) and : f'(-1) given f(-1) = 2
by derivate : <span>4x3+2y2−11=4xy−x
12x² +4yy' = 4y +4xy' - 1
4yy' - 4xy' = - 12x² +4y -1
y' ( 4y - 4x) = 4y -12x² -1 ...(*)
if x = -1 y = 2 subsct in : (*)
y' (4(2)-4(-1)) = 4(2)-12(-1)² - 1
2y' = - 9
y' = - 9/2 = f'(- 1) ( the slope of the tangent )
</span>of the tangent line to the curve <span>at the point (−1,2) is :
y - 2 = (-9/2)(x +1)</span>
Answer:
C
Step-by-step explanation:
A&B are wrong because they imply that x can equal 250, which it can't, it has to be less than 250 so the max x can be is 249.
D is wrong because it is talking about greater than which it is not. It is less than
C is correct
