What is the value of this expression when x=-6 and y= -1/2? 4(x^2+3)-2y

157

Step-by-step explanation:

Given 4(x^2+3)-2y, substitute -6 for x and -1/2 for y:

4([-6]^2 + 3) - 2(-1/2), or

4 (36 + 3) + 1, or

4(39) + 1, or, finally, 157.

is means division by fractions

step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
