I need to verify this function is symmetric with respect to the y-axis. How would I go about doing that? Function: x^4-5x^2+3

is symmetric to the y-axis

Step-by-step explanation:

Given

Required

Determine if it is symmetric

First, we check if the function is even by calculating f(-x)

We have:

This implies that the function is even, and even functions are symmetric to the y-axis.

Hence:

is symmetric to the y-axis

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
