Me with this i beg of u due im desprateee

2. d is not a function

3. c

4. use a graphing calculator ( not rlly sure off the top of my head)

5. b

2. d  A function maps each x value to at most one y value

3.  3 left and 4 down is addition of (-3, -4) so A(5,1), B(4,5) and C(2,3) map to A'(2,-3), B'(1,1), C'(-1,-1)

d

4. Slope of 1, y intercept -5

c

5. b  That's a reflection in the y axis

a. is correct

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
