Answer: D
Step-by-step explanation:
If f(x) = 4x - 2 and g(x) = 2x + 7 then which of the following gives f(g(3))?
g(3) = 2*3+7 = 6+7 = 13
f(g(3))=f(13) = 4* 13 -2= 52 -2 = 50
If you multiply a number and its inverse, you get one. To obtain an inverse, you divide 1 by the number. 0 doesn't have an inverse, because you cannot divide by 0.
First we write the equation of the line in its standard form:
y-yo = m (x-xo)
Where:
m = 2
We choose an ordered pair:
(xo, yo) = (0, 5)
Substituting the values:
y-5 = 2 (x-0)
Rewriting:
y = 2x + 5
Part A:
The average rate of change of the function f (x) over the interval [-4, -1] using the formula:
[f (-1) -f (-4)] / [3]
Part B:
The value of f (-1) is:
y = 2 (-1) +5
y = 3
Part C:
The value of f (-4) is:
y = 2 (-4) +5
y = -3
Part D:
the average rate of change of f (x) over the interval [-4, -1] is
m = [f (-1) -f (-4)] / [3]
m = (3 - (- 3)) / 3
m = (3 + 3) / (3)
m = 6/3
m = 2
