Doug is finding the zeros of the quadratic function $$f\left(x\right)=5x^2+8x+3$$ . His first step is: $$f\left(x\right)=\left(5x+3\right)\left(x+1\right)$$ Which statement describes the correct next step?

Write $$5x+3=0$$ and $$x+1=0$$ and solve

Evaluate $$f\left(x\right)=5x^2+8x+3$$ when $$x=0$$

Evaluate $$5x+3$$ and $$x+1$$ when $$x=0$$

Morgan factored a quadratic function, as shown. $$f\left(x\right)=5x^2-25x-70$$ $$f\left(x\right)=5\left(x^2-5x-14\right)$$ $$f\left(x\right)=5\left(x+2\right)\left(x-7\right)$$ What is true about $$f\left(x\right)?$$

The zeros of $$f\left(x\right)$$ are -2 and 7.

The zeros of $$f\left(x\right)$$ are 2 and -7.

The vertex of $$f\left(x\right)$$ is $$(-2,7)$$

The vertex of $$f\left(x\right)$$ is $$(2,-7)$$

If $$f\left(x\right)=x^2-8x-25$$ , complete the square and determine the minimum or maximum value of the function.

$$f\left(x\right)=\left(x-4\right)^2-41$$ and $$f\left(x\right)$$ has a minimum at $$f(4)=-41$$

$$f\left(x\right)=\left(x-4\right)^2-41$$ and $$f\left(x\right)$$ has a maximum at $$f(4)=-41$$

$$f\left(x\right)=\left(x+4\right)^2-41$$ and $$f\left(x\right)$$ has a maximum at $$f(4)=-41$$

$$f\left(x\right)=\left(x+4\right)^2-41$$ and $$f\left(x\right)$$ has a minimum at $$f(4)=-41$$

A running club is training for a race. The number of kilometers run by 35 members last week is recorded in the dot plot. One more person just reported their total of 15 km. How does this change the statistics that summarize the data?

The interquartile range increases.

Will bought a used car. The value of the car, in dollars, is a function of time, in years, as represented by the expression $$20,000\left(1-0.08\right)^t$$ , where t is the time, in years, since he purchased the car. Which of the following statements describes the meaning of 0.08 in the expression?

the percentage by which the value of the car decreases each year

the percentage by which the value of the car increases each year

the amount of time, in years, that has passed since he bought the car

he function g(x) is shown on the graph. If $$f(x)=\frac{2}{5}x+2,$$ which statement is true when comparing f(x) to g(x).

f(x) is increasing and g(x) is decreasing.

f(x) is decreasing and g(x) is increasing.
