Answer:
The gradient of the function at x = 2 is 56
Step-by-step explanation:
f : f(x² + 3)²
df / dx = 4x(x² +3)
At x = 2
df / dx (= gradient) = 4 x 2 x (2² + 3)
= 8 x (7)
= 56
Let's start with part B. if it was originally 10 cm tall and it goes up 0.5 cm. each day, then we know that to go up one cm it needs two days. With that information we can say that 8*2 = 16. So it needs 17 days to go up 8.5 cm which would make it 18.5 cm tall.
19.95 x 4 = $79.80 dollars

Answer:
Step-by-step explanation:
g(2) = 3(2) - 3 = 6 - 3 = 3
h(3) = 3^2 - 4(3) = 9 - 12 = -3
