Graph of a^x a>1

Let ℝ be the ...

Question

Let $R$ be the set of Real numbers. Define the real function $f : R \to R$ by $f (x) = x + 10$ and sketch the graph of this function.

Open in App

Solution

Step 1:Given $f : R \to R, f (x) = x + 10$

Step $2 :$ Define function
$f$ is defined from the set of real numbers to the set of real numbers.
Hence, Domain is $R$ and range is also $R$

Step $3 :$ Draw graph
Given function is $y = x + 10$
put $x = 0 \Rightarrow y = 10$
put $y = 0 \Rightarrow x = - 10$
put $x = - 5 \Rightarrow y = 5$
This function is a linear function
