Answer:
161
Step-by-step explanation:
Given the functions
f (x) = 2x^2 – 1
g(x) = 3x
we are to find f(g(3))
First look for the composite function f(g(x))
f(g(x)) = f(3x)
f(3x) = 2(3x)² - 1
f(3x) = 2*9x² - 1
f(3x) = 18x² - 1
f(g(x)) = 18x² - 1
Substitute x = 3 into the result
f(g(3)) = 18(3)² - 1
f(g(3)) = 18*9- 1
f(g(3)) = 162-1
f(g(3)) = 161
Hence f(g(3)) is 161

The formula to calculate the slope between two points is equal to
Part A) Determine the slope for the line that passes through the points (3,5) and (−1,−7)
substitute the values in the formula
Part B) Determine the slope for the line that passes through the points given by the table of values
Looking at the given table, take two points
(0,-5) and (2,-3)
substitute the values in the formula
Answer:
She will need $23.87
Step-by-step explanation:
No bc it all adds up to $143.87 so she would need $23.87 more to be able to pay.
Hello!
To dind the Unit Price, we must divide the price by the number of units.
S T O R E A:
56 ÷ 15 = 3.73 (Repeating decimal)
S T O R E B:
32.05 ÷ 15 = 2.1367 (Repeating decimal)
Store B is offering a better price per gallon.
Yes that is the right thing
