Answer:
(g°f)x =16 when x = 5
Step-by-step explanation:
It might be easier to understand if you wrote this the other acceptable way.
g(x) = x^4
f(x) = 2x - 8
g(f(x)) means that in g(x) wherever you see and x you put f(x)
g(f(x)) = (f(x) ) ^ 4 Now put in the general value for f(x)
g(2x - 8) = (2x - 8)^4
You really don't want to expand this (although it would give you the right answer eventually).
g(2*5 - 8) = (2 * 5 - 8)^4
g(2*5 - 8) = (10 - 8)^4
g(2*5 - 8) = 2^4
Answer 16
Answer:
3.143
Step-by-step explanation:
Since you're rounded it to the third decimal, you look at the fourth one. And since the fourth one is 8, ur going round 2, which is the third decimal to 3.
Answer:
B. -11
Step-by-step explanation:
ascending order means least to greatest.
-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7,...
3, -1,
, 13, -11
-11 is the least number because it is the greatest negative number
As given,
"tangent line to f(x) is tangent at (7,5)", therefore f(7)=5.
Line is tangent at (7,5) and passes through (0,4), therefore the slope of the line is the slope of f(x=7) = f'(7).
Answer:
The answer is 8x³ - 34x + 25x - 3
Step-by-step explanation:
(4x − 3)(2x2 − 7x + 1)
8x³ - 28x² + 4x - 6x² + 21x - 3
Collect like terms
= 8x³ - 28x² - 6x² + 4x + 21x - 3
= 8x³ - 34x + 25x - 3
The answer is 8x³ - 34x + 25x - 3
