PLEASE HELP.

3. a)     f(x)=x^2  ---> f=16

3. b)     g(x)=x+5 ---> g=9

3. c)     h(x)=4x-6 ---> h=10

4. a)     f(x)=x^2 > f=0

4. b)     g(x)=x+5 > g=5

4. c)     h(x)=4x-6 > h=-6

Step-by-step explanation:

3. a)     f(4)=4^2  ---> f=16

3. b)     g(4)=4+5 ---> g=9

3. c)     h(4)=4*4-6 ---> h=10

4. a)     f(0)=0^2 > f=0

4. b)     g(0)=0+5 > g=5

4. c)     h(0)=4*0-6 > h=-6

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

students group

step-by-step explanation:

a person who   joins a party or a seminar can explain his feelings about that particular occasion better more than anyone else.

as bella managed a show for the students in the school and invited students to watch that show

hence

students group will be the best group to survey to find this information
