Use the Intermediate Value Theorem to determine whether the polynomial function has a real zero between the given integers. f(x) = 9x5 + 10x3 - 5x2 + 7; between -1 and 0

step-by-step explanation:

is only a line? i think so

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

ummm seems that u didnt post the attachement !
