Find all values of x on the graph of f(x) = –2x^3 + 15x^2 – 12 at which there is a horizontal tangent line. a. x = 0 and x = –5 b. x = 0 and x = 5 c. x = –6 and x = –5 d. x = 1 and x = –1

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

b.-4 units

all you   do is count how many times you move

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

make sure you have version 2.50

try looking in the very back of the book : )
