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:
Step-by-step explanation:
Let x represent the least number of points per day of golf.
This means that his least score for 2 days would be 2x
Jesse played two days of golf. On the second day he got a score of 2 below par or -2. This means that his score on the second day would be
x - 2
His total score for the two days was 8 below par or -8. This means that the total score would be
2x - 8
The score on the first day would be the total score - the score on the second day. It becomes
2x - 8 - (x - 2) = 2x - 8 - x + 2
= 2x - x + 2 - 8
= x - 6
His score on the first day was 6 below par or - 6
