Evaluate for a=-2,b=3,c=-12 and d=-4 ac/b-(a+d)

14

Step-by-step explanation:

ac/b - (a + d) = (-2)(-12)/3 - ((-2) + (-4)) = (-2)(-12)/3 - (-6) = 24/3 + 6 = 8 + 6 = 14

the answer is y = 11.54

hope this : )

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
