If $-2 &lt; x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation PLEASE ANSWER THUS PLEASE
exis [7]

Answer:

(-9,16]

Step-by-step explanation:

we know that

The domain of x is equal to the interval--------> (-2,3]

-2< x \leq 3

All real numbers greater than -2 and less than or equal to 3

Let

y=5x+1

For x=3

y=5x+1\\y=5(3)+1=16

For x>-2

y >5(-2)+1\\y > -9

so

The range of the function is the interval--------> (-9,16]
