Answer:
- 8
Step-by-step explanation:
Note that
is the slope of the tangent at x = a
Differentiate using the power rule
(a
) = na
Given
y = 3x² - 2x + 5, then
= 6x - 2
x = - 1 :
= 6(- 1) - 2 = - 6 - 2 = - 8
14 + x < = 3x....ur inequality
***
the sum means add....so the sum of a number and 14 is 14 + x
is less then or equal....< =
3 times the number....3x
