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.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

60

step-by-step explanation:

there are no answer choices

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
