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

Helen [10]

Answer:

135°

Step-by-step explanation:

To convert <em>Radians </em>to <em>Degrees</em>, you multiply the <em>Radians </em>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.
