Given Function : f(x) = -3x² + 3x + 7
To find out the value of f(8) : Substitute 8 in the function in place of x
⇒ f(8) = -3(8)² + 3(8) + 7
⇒ f(8) = -3(64) + 24 + 7
⇒ f(8) = -192 + 24 + 7
⇒ f(8) = -161
Answer:
X = 3
Step-by-step explanation:
First count the amount of X's. There are 5 and it is plus two. Both sides should be equal in value so you have to set up your equation.
5x + 2 = 17
Then Solve For X
5x + 2 = 17
Subtract 2 from both sides
5x = 15
Divide by 5
X = 3
Check your answer
5(3) +2 = 17
15 + 2 = 17
17 = 17
It is correct!
