Question

If f(x)= 2x2+3x-2, find f(-2)​

Answer 1

$\LARGE\star\mathfrak{\underline{\underline{\red{answer: }}}}$

$f(x) = 2x {}^{2} + 3x - 2$

$f( - 2) = 2( - 2) {}^{2} + 3( - 2) - 2 \\ \\ f( - 2) = 2(4) - 6 - 2 \\ \\ f( - 2) = 8 - 8 \\ \\ \boxed{ \sf f( - 2) = 0}$

Answer 2

Answer:

0

Step-by-step explanation:

putting x=-2

f(-2)​=2(-2)^2+3(-2)-2

=8-6-2

=0

thus f(-2)=0
