Question 54

Which statement about
k(x) = -x$^2$ - 2x + 15 
is true?

Accepted Answer

The zeros are -5 and 3, because k(x) = - (x + 5)(x - 3).

Answer

The zeros are 3 and 5, because k(x) = -(x - 3)(x - 5).

Answer

The zeros are -5 and -3, because k(x)= - (x + 5)(x + 3).

Answer

The zeros are -3 and 5, because k(x) = -(x + 3)(x - 5).

Question 56

The graph of  f(x) = x$^2$ is shown on the grid. Which statement about the relationship between the graph of f and the graph of g(x) = 7x$^2$ is true?

Accepted Answer

The graph of g is narrower than the graph of f.

Answer

The graph of g is 7 units below the graph of f.

Answer

The graph of g is 7 units above the graph of f.

Answer

The graph of g is wider than the graph of f.

Question 57

What are the solutions to
2(x - 7)$^2$ = 32?

Accepted Answer

x = 3 and x = 11

Answer

x = -1 and x = 15

Answer

Question 58

The graph of quadratic function g is shown on the grid. The coordinates of the x-intercepts, the y-intercept, and the vertex are integers. What is the maximum value of g?

Accepted Answer

9

Question 59

Which statement about f(x) = 2x$^2$ - 3x - 5 is true?

Accepted Answer

The zeros are -1 and $\frac{5}{2}$, because f(x) = (x + 1)(2x - 5).

Answer

The zeros are -$\frac{5}{2}$ and -1, because f(x) = (x + 1)(2x + 5).

Answer

The zeros are 1 and $\frac{5}{2}$, because f(x) = (x - 1)(2x - 5).

Answer

The zeros are -$\frac{5}{2}$ and 1, because f(x) = (x - 1)(2x + 5).

Question 60

Quadratic functions q and w are graphed on the same coordinate grid. The vertex of the graph of q is 18 units below the vertex of the graph of w. Which pair of functions could have been used to create the graphs of q and w?

Accepted Answer

q(x) = x$^2$  - 18 and w(x) = x$^2$

Answer

q(x) = x$^2$ + 18 and w(x) = x$^2$

Answer

q(x) = -18x$^2$ and w(x) = x$^2$

Answer

q(x) = 18x$^2$ and w(x) = x$^2$
