When the function f(x) = 4(2)x is changed to f(x) = 4(2)x − 13, what is the effect? (5 points) a
There is no change to the graph because the exponential portion of the function remains the same.

b
The x-intercept is 13 spaces higher.

c
The y-intercept is 13 spaces lower.

d
All input values are moved 13 spaces to the left.

C. The y-intercept is 13 spaces lower.

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

the answer is true.
