How do I figure out b,c, and d

Mathematics

Andrews [41]3 years ago

Answer:

  (b)  domain: (-∞, ∞)

  (c)  f(x) = 3 only at x=1

  (d)  range: (-∞, 3]

Step-by-step explanation:

(b) The domain is the horizontal extent of the region over which the function is defined. The function f(x) is defined for all x, from -∞ to +∞. The arrowheads on the ends of the graph mean the graph extends to infinity in x and y directions from those points (y goes to -∞, while x goes to ±∞).

__

(c) Locate the horizontal grid line y=3 on the graph. Find all the points where it intersects the graph. There is only one: (1, 3). That is, x=1 is the only x-value for which f(x) = 3.

__

(d) The range of the function is its vertical extent. The graph of f(x) extends from y = -∞ up to y = 3, so that is the range.

Step-by-step explanation:

From the graph:

a) f(3) = ?

The vertical line x = 3 intersect the parabola in the point (3, -1).

Therefore f(3) = -1

b) The domain: the set of all real numbers (R) ⇒ x ∈ (-∞, ∞)

c) f(x) = 3, x = ?

The horizonatal line y = 3 intersect the parabola in the point (1, 3) (vertex).

Therefore x = 1 (f(1) = 3.

d) The domain: y ≤ 3 ⇒ y ∈ (-∞, 3]

Solve the equation log4(x + 20) = 3
salantis [7]

Answer:

Step-by-step explanation:

I don not understand what is for 4 here. So there are 2 cases:

Case 1: If you mean: log[4(x+20)]= 3

We know 3 = log(10^3)= log(1000)

So we have log[4(x+20)]= log(1000)

so 4(x+20)= 1000

and x+20 = 1000/4

x+20 = 250 and finally x= 250-20, x=230

The solution is 230.

Case 2; If you mean that 4 is the base of logarithm.

log_{4}(x+20)= 3

and we know that 3=log_{4}(3^{4} )= log_{4}(81)

So we have log_{4}(x+20)= log_{4}(81)

and x+20 = 81

or x= 81-20

x=61

The answer is 61.

Hope that useful for you, both cases.
