C2= 0.25
How to solve that problem

-1.75

Step-by-step explanation:

c 2 = 0.25

I assume the c is just a variable

then

c = 0.25 - 2

= -1.75

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
