Question

If the function is defined as f(a)=a2 + 3a then find f(-1)

Answer 1

Answer:

f ( –1 ) = –2

Step-by-step explanation:

$f(a) = a { }^{2} + 3a \\ f( - 1) = ( - 1) {}^{2} + 3( - 1) \\ f( - 1) = 1 - 3 \\ f( - 1) = - 2$

Answer 2

Answer:

I hope it's helpful please mark me as brainliast.

Step-by-step explanation:

f(-1) = -1 * 2 +3 *(-1)

f(-1) = -2 - 3

Therefore:

f (-1) = -5
