If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?
Oduvanchick [21]
Remember that (g-f)(x) is g(x)-f(x). We know form our problem that f(x)=4-x^2 and g(x)=6x, so:
(g-f)(x)=g(x)-f(x)
(g-f)(x)=6x-(4-x^2)
(g-f)(x)=6x-4+x^2

Now, to find (g-f)(3), we just need to evaluate (g-f)(x) at 3. In other words, we are going to replace x with 3:
(g-f)(x)=6x-4+x^2
(g-f)(x)=6(3)-4+(3)^2

We can conclude that the correct answer is <span>C.6(3) – 4 + 3^2 </span>

deff fn [24]

Answer:

  (a)  F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5)

Step-by-step explanation:

Wherever the function crosses the x-axis, its sign changes. This lets us make a map of the signs of the function, and identify intervals where it is positive and negative.

<h3>Sign changes</h3>

The x-intercepts are said to be at x ∈ {-0.7, 0.76, 2.5}.  These three crossing points divide the graph into four (4) intervals. The sign of the function is given as positive at x=0 and negative at x = 1.9. So, our sign map is ...

  < -0.7 . . . . . negative

  -0.7 to 0.76 . . . . . positive (2 at x=0, for example)

  0.76 to 2.5 . . . . . negative (-5.7 at 1.9, for example)

  > 2.5 . . . . . positive

Choosing from the descriptions, the one that matches is ...

  F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5)

Is 10% of 10% of 100 the same as 20% of 100?
Lelu [443]
No;

20% of 100   =   0.20 x 100   =   20
10% of 10% of 100   =   0.10 x 0.10 x 100   =   1
