Answer:

Step-by-step explanation:

( $\frac{f}{g}$ )(x)

= $\frac{3x+5}{3x^2-x-10}$ ← factor denominator

= $\frac{3x+5}{(x-2)(3x+5)}$ ← cancel (3x + 5), leaving

= $\frac{1}{x-2}$

The denominator cannot be zero as this would make the fraction undefined. Equating the denominator to zero and solving gives the value that x cannot be.

solve x - 2 = 0 ⇒ x = 2 ← excluded value

domain is the set of all real numbers except 2

Suppose g is the function g(x) = 2^x and g : {1, 2, 3} ->{1, 2, 4, 8}

Mashutka [201]

Answer:

Step-by-step explanation:

Given that g is a function from g : {1, 2, 3} ->{1, 2, 4, 8}

by the function

$g(x) = 2^x$

i.e. we have $g(1) =2\\g(2) = 4\\g(3) =8$

Range = {2,4,8} Since there is an extra element 1 in the co domain which is not in range , g is not on to

But g is one to one as 1,2,3 have different images.

The contingency table below gives the counts of students by activities and gender. Band Sports Debate Total Male 105 320 7 432 F

Ber [7]

Answer:

599/711

Step-by-step explanation:

Band Sports Debate Total

Male 105 320 7 432

Female 105 160 14 279

Total 210 480 21 711

P(female or plays sports)

We want the probability that they are female or play sports, but we cannot double count the female sports players, so we subtract them

P(female) + P (sports) - (female and sports)

female/total + sports/total - female sports/ total

279/711 + 480/711 - 160/711

599/711

5 p + 2(3 p - 5) = -29- 8 p<br> Solve for p ( geometry)

Vika [28.1K]

Step-by-step explanation:

5p + 6p -10 = -29 - 8p

11p - 10 = -29 - 8p

+10 +10 +8p

+8p = -19

19p=-19

p=-1
