Find the y-intercepts of the graph of the following quadratic function. If there is more than one intercept, separate them with commas. If there are no x-intercepts type DNE.

Question

Find the y-intercepts of the graph of the following quadratic function. If there is more than one intercept, separate them with commas. If there are no x-intercepts type DNE.

f(y) = 5y^2 - 240

y-intercept(s): __________

Answer 1

Assuming that x is a function of y and

x = 5y² - 240

The y-intercept is at x = 0

0 = 5y² - 240

240 = 5y²

Casn you solve for y and answer?
