If (gx) = 2x^2 -3x, evaluate, expand and simplify completely.
g(-2)
g(-c)
g(d^2)
g(-2)
Hello,Originally Posted by batman123
first: The last problem is the same as the first problem, so I'll not do that again.
second: Plug in the given value for x and calculate:
$\displaystyle g(-2)=2 \cdot (-2)^2-3 \cdot (-2)=2 \cdot (4)+6=14$
$\displaystyle g(-c)=2 \cdot (-c)^2-3 \cdot (-c)=2 \cdot c^2+3c$
$\displaystyle g(d^2)=2 \cdot (d^2)^2-3 \cdot (d^2)=2 \cdot (d^4)-3d^2$
