What is the interval in which both f(x) and g(x) are positive?
1 answer:
The positive interval of a function is when the function has positive values.
<em>The interval in which both f(x) and g(x) are positive is </em><em />
<em />
<em />
From the given graphs of g(x), we have the following observations.
- <em>The graph of f(x) crosses the x-axis at </em>
<em />
- <em>The graph of g(x) also crosses the x-axis at </em>
<em />
<em />
This means that:
<em /><em> --- for both functions</em>
But when x increases, the value of y becomes positive,
<em>So, the positive interval of f(x) and g(x) is </em><em />

Given:
is in xy plane and
is in the direction of k.
|a|=6 units, |b|=3 and θ = 90°
|a × b| = |a| × |b| sinθ
= |a| × |b| sin90°
= 6 × 3 × 1
|a × b| = 18

In this case,
x-component of is positive.
y-component of is negative.
z-component of is zero.
