can someone correct this for me please.
Directions: Evaluate each function for the value specified.
f (x)=x^2+7c+10, f (-2)
so then this is what i did:
f(-2)=-2^2-7(-2)+10
= 4+14+10
= 28
so then that means that f(-2) = 28
sorry the formula should read. f(x)=x^2+7x+10 i need to find for f(-2)
(-2)=-2^2-7(-2)+10
= 4+14+10
= 28
If that is x^2+7x+10 then
-2^2+7(-2)+10=
4-14+10
??
To evaluate the function f(x) = x^2 + 7x + 10 for the value specified, f(-2), you correctly substituted -2 for x in the function. However, there seems to be a mistake in your calculation.
Let's go through it again step by step:
1. Substitute -2 for x in the function: f(-2) = (-2)^2 + 7(-2) + 10.
2. Simplify the expression inside parentheses: f(-2) = 4 + 7(-2) + 10.
3. Multiply: f(-2) = 4 - 14 + 10.
4. Add and subtract: f(-2) = -6 + 10.
5. Finally, add: f(-2) = 4.
Therefore, the correct evaluation of f(-2) is 4.
