Evaluate f(×)=5×+8 at f(-3)
All you do is substitute -3 for x.
5(-3) + 8 = 0
To evaluate f(x) = 5x + 8 at f(-3), substitute -3 for x in the function:
f(-3) = 5(-3) + 8
Now, we can simplify this expression:
f(-3) = -15 + 8
Combining like terms:
f(-3) = -7
Therefore, f(-3) is equal to -7.
To evaluate f(x) = 5x + 8 at f(-3), we need to substitute -3 for x in the function and compute the result.
First, let's substitute -3 for x in the function:
f(-3) = 5(-3) + 8
Next, we perform the calculations:
f(-3) = -15 + 8
Finally, we simplify:
f(-3) = -7
Therefore, f(-3) = -7.
