Question

Consider the following function.

f(x) = 3/2x + 4

Using the given function, plot all the ordered pairs for the values in the domain below.

{ -8, -4, -2, 0, 2, 4}

Answer 1

we have that
f(x) = (3/2)*x + 4

case 1) for x=-8
f(-8) = (3/2)*(-8) + 4--------> -8
point (-8,-8)

case 2) for x=-4
f(-4) = (3/2)*(-4) + 4--------> -2
point (-4,-2)

case 3) for x=-2
f(-2) = (3/2)*(-2) + 4--------> 1
point (-2,1)

case 4) for x=0
f(0) = (3/2)*(0) + 4--------> 4
point (0,4)

case 5) for x=2
f(2) = (3/2)*(2) + 4--------> 7
point (2,7)

case 6) for x=4
f(4) = (3/2)*(4) + 4--------> 10
point (4,10)
