Answer:
Step-by-step explanation:
<u>Function given:</u>
Evaluate the function for an input value of 3
<u>Input value is x = 3, output value is:</u>
- f(3) = -4(3²) – 3(3) – 5 = -4(9) - 9 - 5 = -36 - 14 = -50
- f(3) = -50
Yes, for every value of x, there is only one value of y. This means that y is a function of x.
14x0.75=10.5
15-10.5=4.5
so she will get $4.50c
Hope this helps! :D
Answer:
Hello,
Step-by-step explanation:
Roots are -2 and 4
y=k*(x+2)(x-4)
Vertex = (1,-9) is a point of the parabola
-9=k*(1+2)(1-4) ==> k=1
Equation of the parabola is y=(x+2)(x-4)
But you don' t have given the graphs !!!!
