Fast! Which of the following are characteristics of the graph of the square root

Mathematics
1 answer:
svetlana [45]3 years ago
3 0

Answer:

Only choices B and C are correct.

Step-by-step explanation:

The square root parent function is f(x)= \sqrt{x}.

The function f(x) is not a linear function, therefore it's graph cannot be a straight line. This rules out choice A.

The function f(x) is defined at x=0 because f(0)= \sqrt{0} =0. This means that choice B is correct.

The function f(x) is only real for values x\geq 0, because negative values of x give complex values for f(x). This means that choice C is correct.

The function f(x) can take only positive values which means it is confined to only the I quadrant, and is not defined in quadrants II, III, and IV. This rules out Choice D.

Therefore only choices B and C are correct.

Use the Remainder Theorem to find the remainder: (16x^4 – 8x^3 – 4x + 1) ÷ (2x + 1)
vodka [1.7K]

Answer:

5

Step-by-step explanation:

This illustrates the Remainder Theorem. If a polynomial f(x) is divided by x−a , the remainder is the constant f(a) , and f(x)=q(x)⋅(x−a)+f(a) , where q(x) is a polynomial with degree one less than the degree of f(x) . Synthetic division is a simpler process for dividing a polynomial by a binomial.

Lim x approaches 0 (1+2x)3/sinx
jok3333 [9.3K]

Interpreting your expression as

\dfrac{3(1+2x)}{\sin(x)}

when x approaches zero, the numerator approaches 3:

3(1+2x) \to 3(1+2\cdot 0) = 3(1+0) = 3\cdot 1 = 3

The denominator approaches 0, because \sin(0)=0

Moreover, we have

\displaystyle \lim_{x\to 0^-} \sin(x) = 0^-,\quad \displaystyle \lim_{x\to 0^+} \sin(x) = 0^+

So, the limit does not exist, because left and right limits are different:

\displaystyle \lim_{x\to 0^-} \dfrac{3(1+2x)}{\sin(x)}= \dfrac{3}{0^-} = -\infty,\quad \displaystyle \lim_{x\to 0^+}\dfrac{3(1+2x)}{\sin(x)}= \dfrac{3}{0^+} = +\infty

3 = −2∣ 1 — 4 s − 5 ∣ + 3
artcher [175]

Answer:

s=1

Step-by-step explanation:

3=-2(1-4s-5)+3

3=-2+8s+10+3

3=8s+11

3-11=8s

8=8s

8/8=s

s=1

hope it helps you!!
