Use the graph of the function \$f\$ to answer the following questions.For what values of \$x\$ does \$f(x)=3 ?\$

First graph the two functions. Then use the method of successive approximations to locate, between successive thousandths, the \$x\$-coordinate of the point where the graphsintersect.Use a graphing utility to draw the graphs as well as to check your final answer. \$\$y=x^{3}-5 ; y=2 x-3\$\$

Okay. First we use the vertical line test. Mm hmm. Okay. First step you seem the vertical line past to determine whether the function whether the graph represents a function. Yeah. Okay. So the vertical line test can be used to determine whether a graph represents a function. If we draw any vertical line that intersects a graph more than once. Then the graph does not define the function because the function has only one output value for each input value. The next step is we’re using horizontal lines. Yeah. To determine If each function is 1- one. Okay. So if no horizontal line, there’s sex, a graph of the function f in more than one point. Then the function is 1-1 mm hmm.…
