Question

cat - culate
the height of the cats eyes is $h(x) = 2x + 3$, where $x$ is the width of the base.
calculate the value of each function notation expression.

expression	eye height (in.)
$h(3)$
$h(7.5)$

check my work
$h(x) = 2x + 3$

Explanation:

For \( h(5) \):

Step1: Substitute \( x = 5 \) into \( h(x) \)

\( h(5)=2\times5 + 3 \)

Step2: Calculate the result

\( 2\times5=10 \), then \( 10 + 3 = 13 \)

For \( h(3) \):

Step1: Substitute \( x = 3 \) into \( h(x) \)

\( h(3)=2\times3 + 3 \)

Step2: Calculate the result

\( 2\times3 = 6 \), then \( 6+3 = 9 \)

For \( h(7.5) \):

Step1: Substitute \( x = 7.5 \) into \( h(x) \)

\( h(7.5)=2\times7.5 + 3 \)

Step2: Calculate the result

\( 2\times7.5 = 15 \), then \( 15 + 3 = 18 \)

Answer:

• For \( h(5) \): \( 13 \)
• For \( h(3) \): \( 9 \)
• For \( h(7.5) \): \( 18 \)
