can someone check my answers if f(x)=4x-3 find f(-1) f(-1)=4*(-1)-3=-4-3= -7

That's right.

correct.

thank you both

To check if your answer for f(-1) is correct given f(x) = 4x - 3, you need to substitute -1 for x in the equation and evaluate the expression.

So, let's substitute -1 into the equation:

f(-1) = 4(-1) - 3

Now simplify the expression:

f(-1) = -4 - 3
f(-1) = -7

Therefore, your answer for f(-1) is correct. Well done!
