If f(x) = 3x, what is f(4)?

Mathematics
1 answer:
dimulka [17.4K]3 years ago
3 0

Answer:

f(4) = 12

Step-by-step explanation:

Substituting 4 for x in f(x) = 3x, we get f(4) = 3(4) = 12.  We conclude that "the value of the function f(x) = 3x at x = 4 is 12."

slava [35]

Answer:

(x, y ) → (x - 4, y )

Step-by-step explanation:

A horizontal move of 4 to the left means subtract 4 from the x- coordinate, leaving the y- coordinate unchanged, thus

(x, y ) → (x - 4, y ) ← translation rule

5/9(F-32)= -62.1 what is F?​
nlexa [21]

Answer:

F = -79.78

Step-by-step explanation:

You need to set F by itself

5/9(F-32) = -62.1

multiply the reciprocal of 5/9 on both sides to eliminate 5/9. The reciprocal is 9/5

-62.1 times 9/5

= -111.78

F-32 = -111.78

add 32 on both sides to get F by itself.

-111.78 + 32 = -79.78

Your final answer

What is the y-intercept of the line y + 11 = –2(x + 1.5)? y-intercept =
Lana71 [14]

y + 11 = –2(x + 1.5)

y=mx+b

multiply the bracket by -2

(-2)(x)=-2x

(-2)(1.5)=-3

y+11=-2x-3

move +11 to the other side

sign changes from +11 to -11

y+11-11=-2x-3-11

y=-2x-14

m is also the slope

b= y-intercept

Answer:

y-intercept=-14

Which equation represents h(x)?
GarryVolchara [31]

Answer:

Step-by-step explanation:

You might find this easier if you change h(x) to y. It might look more familiar.

you are given 1 point and that is (-1,1). What that means is when x = -1,

y = 1

You have written this as though y is linear. It is not. The power is 1/3, not 1.

Let us try B which is what I think the answer is.

y = (x + 2)^(1/3)

Put x = -1 on the right hand side.

y = (-1 + 2)^(1/3)

y = (1)^(1/3)            

The cube root of 1 is 1.

So the answer is

y = (x + 2)^(1/3)
