math help pleez!!! 10 points!?

Question

f(a)=3(squareroot)4a


xplain how u do tht 1



and these also

t=(squareroot)2x

THANX!!!

i dont know wat ur supposed 2 do but its sumthing with radicals

Its about simplifying properties of radicals
- we have 2 graph it and find the domain and range

THANX!!`

Answer 1

You actually need ordered pairs(x,y) so u can graph the given functions. In this case, the values of a will be your x values while the corresponding results for the values of f(a) will be your y; and here's how to do it:

1.) f(a)=3(squareroot)4a

step1: assign any values for a to get the corresponding values of f(a)
if a=1, then substitute the value of a to the function

f(1)=3(sqroot)4(1)
=3(sqroot)4
=3(2) since the square root of 14 is 2
f(1) = 6

if a=4, then substitute it to the given function
f(4)=3(sqroot)4(4)
=3(sqroot)16
=3(4)
f(4)=12

if a=0
f(0)=3(sqroot)4(0)
=3(sqroot)0
f(0) =0

therefore the ordered pairs determined are:
(1,6) (4,12) (0,0)
since you now have the ordered pairs or the corresponding values of x's and y's, u can therefore graph the function

Regarding the domain and range:

the domain which are actually the assigned values of a: D={1,4,0,...} or a set of x's such that x=0 or any positive real nos.

the range are actually the corresponding calculated values of
f(a): R={6, 12, 0,...} or a set of all y's such that y= 0 aor any positive real number


do the same with problem no.2, just assign any values for x (w/c are restricted to 0 and positive real numbers) and then u will get the corresponding values of t
ordere pair will be (x,t)=(x,y)

Answer 2

You can draw a graph with both the equations. You just need to insert different values for a in the first and for x in the second and solve for f(a) and t respectively. These will give you the x and y co-ordinates for your graph

Answer 3

one million) Convert the equation to slope-intercept style. -2x ? 4y = -20 -2x = -20 + 4y -2x + 20 = 4y y = -½x + five zero = -½x + five -five = -½x x = 10 two) y ? four = two(x + three) y = 2x + 6 + four y = 2x + 10 You can see that the graph of y ? four = two(x + three) is shifted 10 models up.

Answer 4

what do you want us to do ?...whats the objective
