Answer:
36
Step-by-step explanation:
Since f(x) varies directly with x, f(x) can be expressed alternatively as \[f(x) = k * x\] where k is a constant value.
Given that f(x) is 72 when the value of x is 6.
This implies, \[72 = k * 6\]
Simplifying and rearranging the equation to find the value of k:
k = \frac{72}{6}
Hence k = 12
Or, \[f(x) = 12 * x\]
When x = 3, \[f(x) = 12 *3 \]
Or in other words, the value of f(x) when x=3 is 36
Answer:
35
Step-by-step explanation:
92/100
The first 2 digits are 92, 92/100 is 0.92
Answer:
f(1) =2
Step-by-step explanation:
f(x) = 4^x-
2
Let x=1
f(1) = 4^1 -2
=4-2
=2
