Evaluate each function.<br> 1) f(x) = x2 + 4x; Find f(-7)
katrin [286]

Answer:

The answer is -77

Step-by-step explanation:

Ok, so assuming by x2 you mean x squared, I will solve this. So basically when you have a function, f(-7) would mean that you would have to replace all the x's in the equation with -7. So let's write that out. that would be f(-7) = -7^2 + (-7*4). So now according to PEMDAS, you would solve the exponent first, and -7^2 is equal to -49, because when you solve it you would do -(7^2), which is -(49), which is then -49. So now you have f(-7)= -49+ (4*-7). Solving for (4*-7), you get -28. This leaves you with -49 + (-28), which is -49 - 28. Simplifying that, you get the answer, which is -77.

PtichkaEL [24]
Draw a right triangle.

tan(theta) = \frac{opposite}{adjacent}

tan(theta) = \frac{10}{14}

Arctangent (tan^-1) can be used to find theta.

tan^{-1}(\frac{10}{14})=theta

theta\ is\ approx\ \boxed{36\ degrees}
