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!
