there is no question my dude
Step-by-step explanation:
Answer:
Step-by-step explanation:
f(x) = 2x - 3
f(-9)= 2(-9) - 3 = -18 - 3 = -21
f(-3) = 2(-3) - 1 = -6 - 1 = -7
f(1)= 2(1) - 3 = 2 - 3 = -1
Answer:
f'(12)= 5
Step-by-step explanation:
Use the data in the table to approximate f ′(12).
x 3 4 7 11 13
f(x) 2 8 10 12 22
f'(12) is nothing but the slope at x=12
To find slope at x=12 we two points from the table x=11 and x=13
(11,12) and (13,22)
Slope formula =
(11,12) is (x1,y1) and (13,22) is (x2,y2)
f'(12) =
so f'(12)= 5
