Plug in the -3 for x
F(-3)=2(-3)^3+4(-3)^2
F(-3)=2(-27)+4(9)
F(-3)=-54+36
F(-3)= -18

Hope this helped :)

F(-3) = 2(-3)^3 + 4(-3)^2

f(-3) = 2(-27) + 4(9)

f(-3) = -54 + 36

f(-3) = -18

Answer:

135°

Step-by-step explanation:

To convert Radians to Degrees, you multiply the Radians amount by $\frac{180}{\pi}$ .

Thus, we get $\frac{3\pi }{4}$ * $\frac{180}{\pi}$

We then get $\frac{540\pi }{4\pi }$ , which simplifies into 135 degrees.
