PLEASE HELP IF ANYONE KNOWS HOW TO DO THIS PLEASE HELP! Given the function:
f(x) = -2° + 2x² - 4

a) Explain how to evaluate f(-4). Include the value in your description.

b) Explain how to evaluate f(-3). Include the value in your description.

C) True or False? A zero of f(x) lies on the interval (-4,-3). Explain how you came to this conclusion.

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
