If F(x)=x^2-x+1 and g(x)=-3x+6, what is the product of f(-1) and g(3)?
Help please.
f(-1)=(-1)^2 -(-1)+1=3
g(3) =-3(3)+6=-3
3 times -3 = 9
the answer is -9 not 9
To find the product of f(-1) and g(3), we need to evaluate f(-1) and g(3) separately, and then multiply the values.
First, let's evaluate f(-1) using the given function f(x) = x^2 - x + 1. To do this, substitute -1 for x in the function:
f(-1) = (-1)^2 - (-1) + 1
= 1 + 1 + 1
= 3
Next, let's evaluate g(3) using the given function g(x) = -3x + 6. Substitute 3 for x in the function:
g(3) = -3(3) + 6
= -9 + 6
= -3
Now that we have the values of f(-1) = 3 and g(3) = -3, we can find their product by multiplying them:
Product = f(-1) * g(3)
= 3 * (-3)
= -9
Therefore, the product of f(-1) and g(3) is -9.
