Step-by-step explanation: If g(a) = a² + 1, then g(-2) = (-2)² + 1
which simplifies to 4 + 1 or 5.
Remember to always use parenthses when
substituting your given value in for a.
Answer:
first C then B
Step-by-step explanation:
The distance Raphael needs to travel goes down by time. Therefore the y-value (the amount of distance) will go down as the x-value (the amount of time) will go up. So C.
The speed of the rollercoaster is increasing as time goes by. Therefor the y-value (the speed) will go up and the x-value (the amount of time) will also go up. So B.
Time is almost always moving forward so you can almost always assume x will go up.
Your answer is b and c :)
Answer: First we evaluate g(0), then plug the value into f(x).
g(0) = -2(0) + 7 = 7.
Thus, we need to do f(7).
f(7) = 3(7)-4 = 21 - 4 = 17.
