Answer:
Step-by-step explanation:
1). f(x) = 2x
f(-3) = 2(-3) = -6
f(1) = 2(1) = 2
f(4) = 2(4) = 8
Ordered pairs → (-3, -6), (1, 2), (4, 8)
2). f(x) = 2x + 1
f(-3) = 2(-3) + 1 = -5
f(1) = 2(1) + 1 = 3
f(4) = 2(4) + 1 = 9
Ordered pairs → (-3, -5), (1, 3) and (4, 9)
x -3 1 4
f(x) -5 3 9
3). f(x) = -3x
f(-3) = -3(-3) = 9
f(1) = -3(1) = -3
f(4) = -3(4) = -12
Ordered pairs → (-3, 9), (1, -3), (4, -12)
x -3 1 4
f(x) 9 -3 -12
Answer:
7*2=14 8x=8*8=64*2
Step-by-step explanation:
Thats how you basically do it now try it!
When adding fractions you need a common denominator so lets look at what "fractions" we are dealing with:2/3 1/6 and 1/4.
Answer:
y = - 3x - 2
Step-by-step explanation:
The function is linear and can be expressed in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (- 1, 1) ← 2 ordered pairs from the table
m = = = = - 3 , then
y = - 3x + c
To find c substitute any ordered pair into the equation
using (0, - 2 ) , then
- 2 = - 3(0) + c = 0 + c ⇒ c = - 2
y = - 3x - 2 ← function rule
