1. Start with the given function: f(x) = x + 2.
2. Substitute x+7 for x in the function: f(x+7).
3. Calculate f(x+7): f(x+7) = (x+7) + 2.
4. Simplify the expression: x + 7 + 2 = x + 9.

Answer: F(x+7) = x + 9.

Exercise The temperature T in degrees Celsius of a chemical reaction is given as a function of time t, expressed in minutes, by the function defined on ΒΏ by: T (t )=(20 t +10)eβˆ’0.5t. 1) What is the initial temperature? 2) Show that T' (t )=(βˆ’10 t +15)eβˆ’0 .5t. 3) Study the sign of T' (t ), then draw up the table of variations of T . We do not ask for the limit of T in +∞. 4) What is the maximum temperature reached by the reaction chemical. We will give an approximate value to within 10βˆ’2. 5) After how long does the temperature T go back down to its initial value? We will give an approximate value of this time in minutes and seconds.

The car with an irresponsible driver starts to brake when it goes through a red light. When passing the traffic light, he does so at a speed of 115 kph in the right lane. Further ahead, 70 meters from the traffic light, a child is crossing the street and falls. If the effect of the car's brakes is equivalent to a deceleration of magnitude 5.7m/sΒ². Is the child hit by the car or not? How far from the traffic light does the car stop?
