explain how to sketch a graph of the function f(x) = x3 + 2x2 – 8x. be sure to include end-behavior, zeroes, and intervals where the function is positive and negative.

The degree of the function is odd and the leading coefficient is positive – so the function goes to negative infinity as x goes to negative infinity and to positive infinity as x goes to positive infinity.

The zeroes are –4, 0, and 2, all with multiplicity 1.

The function is negative from negative infinity to –4 and from 0 to 2.

The function is positive from –4 to 0 and from 2 to infinity.

Step-by-step explanation:

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
