Answer:
A) -3
B) 7
C) -13
D) 5x+2
Explanation:
For A, B, and C substitute the value stated in the parenthesis.
A) f(0) means to find the value when x=0, so we substitute 0 where x is in the function.

Then use PEMDAS and multiply first and then subtract 3 from the product.

B) Take the same steps as before with a different value. Substitute 2 for x.

C) Also the same thing as the previous problems. Substitute -2 for the value of x.

D) Similar to above substitute x+1 where x is.

Then distribute 5(x+1) to get

Then simplify the equation
