Please someone help me quickly

Step-by-step explanation:

The domain tells us the possible x values in a function.

Look at the function, it has a open circle at x=-4 and it has a closed circle at x=6. This means that we can any value of number that is between negative 4 and 6. It cannot be negative 4 since it has a open circle so our domain is

The range is possible y values. Looking at the function, the lowest y value is at y=-3 and it has a open circle,

the highest y value is 3 and it at a closed circle.

This means we can have any y value from -3 and 3 but not -3 since it at a open circle so our range is

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
