Answer:
= 2x + 3
Step-by-step explanation:
The gradient function is the derivative
Differentiate using the power rule
(a
) = na
and ( constant ) = 0
Given
y = x² + 3x + 1, then
= 2
+ 3
+ 0 = 2x + 3
= 2x + 3 ← gradient function
Answer:
a = c + 16
Step-by-step explanation:
a = b + 12
b = c + 4
Solve for b in the first equation.
a = b + 12
a - 12 = b
Put b as a - 12 in the second equation and solve for a.
a - 12 = c + 4
a = c + 4 + 12
a = c + 16
